How do I update a field in the Lightning List: component?

Hi,my code contains two lightning: datatable where I pass two lists respectively. The first list "prodList" I need to show the products in the first lightning: datatable the second checks my cart. Having said that I have a question, when I go to select a product in the table as seen in the picture, a popup appears with a lightning in it: input which I need to make the user enter the desired quantity of that product. My list contains an "Available Quantity" field, when I go to select a product and enter the quantity you want it makes me a check where I subtract the quantity chosen by the user from the "Available quantity", how do I update the list and automatically check the updated value in the Available Quantity?

Hi Luigi,

It would be difficult to understand without narrow down scenerio.  Kindly provide narrow down scenerio and were you are stuck currently.

Thanks,
