I have product page on which I have shop now btn. When user clicks on this button, page opens cart drawer with custom ajax template content.
I rewrited click event with my own logic. I use AJAX and send request for adding product by myself. Products are adding but is not showing in the cart drawer. Only after reloading page it is appearing.
Question is to can I refresh cart content? I'm trying to past content template via inner html. But it is looks like not liquid format.
Here is the template
<script id="CartTemplate" type="text/template">
{% render 'banana-stand-cart-top-container' %}
{% raw %}
<div class="drawer__scrollable">

So, need fire some event that you can find in your theme.js file. In my case I needed to add this:
document.dispatchEvent(new CustomEvent('cart:build', {
detail: {
cart: cart
}
}));
