Price update after clicking on the button in the product module

[graficzny.chlopak 1]

Hello, i have problem.

I am writing a module that will change the price depending on what inputs the client chooses. I need to change the price for a product if the user clicks, for example:

gold input + 15 euro add to price, silver input + 30 euro add to price.

Should I overwrite the controller or can I do it from the module that I am writing with js?

Thank you in advance for your help
