JS related work. Fixing cart page loads and remove bundle products.

Hello, In an online store, we have added a product bundle in the cart, and a button also to remove that product bundle from the cart. But that remove button is not working properly. Another issue is that page is that the cart page is loading more than once when we add a product bundle to the cart. your job is: 1. To make the 'Remove bundle' button work properly, and it should remove all products in the cart from that bundle only and should not reload again and again. 2. To make the cart page load only once after adding a product bundle to the cart. Should be easy for you if you are good at JS and if you know what you are doing. Do not bid if you are not a JS developer. we do not have time and this is why outsourcing this task.
