Cart not updating?

Question

WordPress

I want to hang a content update event on the button on the cart page, but for some reason nothing works, for example, I broadcast or via , but nothing happens., what am I doing wrong? UPD I found out that the fact is that I added a shipping calculator, but I still don’t understand why this is happening $("[name='update_cart']").trigger("click");$( document.body ).trigger( 'update_checkout' );
