Shopping cart -> main page problem(increase/decrease)

[GalazKit]

Hi,
I have a problem related to Shopping cart. 

I implemented the option to increase / decrease the number of products in the card view( it is the same function as in Proceed To Checkout). - Screen 1

In "Proceed to checkout" the function works fine, adds products and refreshes every time.

but on the main page you can only add the product once and it will refresh only once, in addition, the buttons for increasing and decreasing the amount disappear. I suspect it's Ajax's fault, but I'm not sure. Do you have any solution? - Screen 2

PS. When I enter the manual number into the field without any buttons and confirm it with the enter button, the number of products will be saved correctly
