shopify:section:load doesn't working at all

Hello guys, I have a problem where my shopify section is not re-rendering when I add changes. I read about about shopify:section:load event but when I add it, js is not executing at all. For example:

<script>

jQuery(document).on('shopify:section:load', function(event) {
console.log('hello');
});

</script>

This should work but nothing is logged in my console.

First I thought it’s maybe a jquery problem but when I add

console.log(jQuery().jquery);

outside of event, it’s showing correct jquery version in console.

Any Thoughts?
