Update product description when cart amount is updated

[WoutervdMeer]

Dear community,

I am currently making technical changes to my website.

For some bundle products I want to dynamically show the amount of products within the bundle they have in their cart, on the product page (the attached).

This amount is a multiplication of the cart quantity and the bundle unit amount. (see code below)

Code:

{% if product.handle contains "bundle" %}

<hr>
{%- assign cart_qty = cart | item_count_for_variant: product.selected_or_first_available_variant.id -%}

<h4>Momenteel bestaat jouw DIY pakket uit (<strong>{{cart_qty}} m2</strong>):
<style><!--
table th, td {padding: 0.3em !important;}
--></style>
<style><!--
table tr:nth-child(odd){background: #F3F3F3; tr:nth-child(even){background: #efefe9;}
--></style>

{% assign current_variant = product.selected_or_first_available_variant %}
{% assign bundled_variants = current_variant.metafields.simple_bundles.bundled_variants.value %}
{% unless bundled_variants == blank %}
<div class="product__description rte">
{% for bundled_variant in bundled_variants %}
<table width="100%">
<tr> <td> <li>
{{ bundled_variant.quantity_in_bundle | times: cart_qty }} x
{{ bundled_variant.product_title }}
{% unless bundled_variant.variant_title == 'Default Title' %}
({{ bundled_variant.variant_title }})
{% endunless %}
</li> </td></tr> </table>
{% endfor %}
</div>
{% endunless %}
</h4>
<hr>
{% endif %}

Everything works properly but the amounts in the table are not updated if the cart amount is updated.

Does someone know how to do/trigger this? I thought this is a javascript thing.

The application for the bundles is 'Simple Bundle'.

Looking forward to the responses.

Kind regards,

Wouter vd Meer
