Need Javascript help for my free shipping progress bar

I have made a shipping progress bar on the product page (with help from Coding With Jan on YouTube) which updates with ajax when someone adds to cart, or updates/removes the quantities from the cart drawer.

The problem that I have is I have made a green progress background that progresses as the customer add items to their cart e.g.

shipping bar.jpg

 

 

 

 

The shipping amount updates fine, and the success message when the shipping threshold is met also works fine with ajax, but the green bar will not update without a page refresh.

Here it the liquid code.

 

 

 

 

 

 

{% if section.settings.is_free_shipping_bar %}
            {% assign promote_txt = section.settings.promote_free_shipping_txt | escape %}
            {% assign unlocked_txt = section.settings.unlocked_free_shipping_txt | escape %}
            {% assign threshold = section.settings.free_shipping_threshold | times: 100 %}
  			{% assign shipping_quotient = settings.free_shipping_threshold | times: 100 | divided_by: 100 %}
  			{% assign shipping_procent = cart.total_price | divided_by: shipping_quotient | at_most: 100 %}
            {% assign value_left = threshold | minus: cart.total_price %}
            {% assign value_left_money = value_left | money %}
      <style>
        .shipping-bar {
          background-color: {{ section.settings.color_bg }};
          position:relative !important;
        }
        
        .shipping-bar-success {
          background-color: {{ section.settings.success_color_bg }};
        }
 
        .shipping-bar--link:hover {
          {% assign brightness = section.settings.color_bg | color_brightness %}
 
          {% if brightness <= 192 %}
            {% assign lightenAmount = 255 | minus: brightness | divided_by: 255 | times: 16 %}
            background-color: {{ section.settings.color_bg | color_lighten: lightenAmount }};
          {% else %}
            {% assign darkenAmount = 255 | divided_by: brightness | times: 8 %}
            background-color: {{ section.settings.color_bg | color_darken: darkenAmount }};
          {% endif %}
        }
 
        .shipping-bar__message {
          color: {{ section.settings.color_text }};
          padding: 10px 0;
          font-size: max(calc(var(--typeBaseSize) - 6px), 11px);
		  letter-spacing: 0.2em;line-height: 1.42;
 		  text-transform: uppercase;
          font-weight:bold;
          text-align: center;
          position: relative !important;
        }
        
        .free-shipping__progress {
          position:absolute !important;
          background-color: #25a799;
          left: 0!important;
          top: 0!important;
          height: 100% !important;
          width: {{shipping_procent}}%;
        }
      </style>
        
             <div class="shipping-bar" data-promote="{{promote_txt}}" data-unlocked="{{unlocked_txt}}" data-threshold="{{threshold}}" data-quotient="{{shipping_quotient}}" data-procent="{{shipping_procent}}">
               <div class="free-shipping__progress"></div>
  				{% if value_left <= 0 %}
                <p class="shipping-bar-success shipping-bar__message">{{unlocked_txt}}</p>
               {% else %}
                <p class="shipping-bar__message">{{promote_txt | replace:'[value]' , value_left_money}}</p>
               {% endif %}
            </div>
            
  
        {% else %}
  		</div>
          {% endif %}

 

 

 

 

 

 

 

 Here is my javascript.

 

 

 

 

 

 

document.addEventListener('page:loaded', function() {
    
theme.ShippingBar = (function() {
  
  var bar = document.querySelector('.shipping-bar');
 
  if(bar)
  {
  var promote_txt = bar.dataset.promote;
  var unlocked_txt = bar.dataset.unlocked;
  var threshold = bar.dataset.threshold;
  var shipping_quotient = bar.dataset.quotient;
  var shipping_procent = bar.dataset.procent;
  }
  
  function update()
  {
    if(bar)
    {
    $.getJSON('/cart.js').then(
    
      function(cart) {
      	
        var shipping_quotient = threshold * 100 / 100;
        var shipping_procent = cart.total_price / shipping_quotient;
        var value_left = threshold - cart.total_price;
        var value_left_money = theme.Currency.formatMoney(value_left,theme.moneyFormat);
        
        
        if(value_left >= 0){
        	bar.innerHTML =  '<div class="free-shipping__progress">' + '</div>';
        }
        
        if(value_left <= 0){
        	bar.innerHTML =  '<p class="shipping-bar-success shipping-bar__message">' + unlocked_txt + '</p>';
        }
        else{
          bar.innerHTML = '<p class="shipping-bar__message">' + promote_txt.replace('[value]',value_left_money) + '</p>';
        }
      }
      
    );      
    }
  }
  return { update:update }
}) ();

  });

 

 

 

 

 

 

Here is the Schema.

        "type":"checkbox",
        "label":"Enable Free Shipping Progress Bar",
        "id":"is_free_shipping_bar",
        "default":false
    },
    {
        "type":"text",
        "id":"promote_free_shipping_txt",
        "label":"Free Shipping Promotion Text"
    },
    {
        "type":"text",
        "id":"unlocked_free_shipping_txt",
        "label":"Free Shipping Success Message"
    },
    {
        "type":"range",
        "id":"free_shipping_threshold",
        "label":"Free Shipping Success Threshold",
        "min":0,

      "label":"Bar",
      "default": "#f54337"
    },

I have built the site with the Impulse Theme as a base. Any help would be greatly appreciated.
