I want to change popover content after a click to show cart items. Debug the code. The popover is still saying title: “Your Cart” and content: “Hello”. I don’t know how to fix it. I am currently working on a django project and facing an issue with dynamically changing the content of a popover after a click event. The popover is meant to display the items in the user’s shopping cart.
