Why isn't jQuery hiding elements on my site?

[blueberry-pay]

Hi

I am using review app and I want to hide some elements such as buttons which is displayed on my site.

The code is imported in my product.liquid after my product-templage.liquid.

Within the product.liquid I add:

  {% unless customer %}

<script>

$(window).load(function(){

        $('.wc_review_form_btns').hide();

});

  </script>

{% endunless %}

But it does not work. If I just add the 

$('.wc_review_form_btns').hide();

within the browser it does work.

Can someone help why it is not working within product liquid?
