popup add to cart

[guardiano78]

Hello,
i have a component that works with "sublayouts/products_horizon.php" for display products list:
http://www.eyenet.it/index.php/catalogo/vmcategory/12-accessori-compatibili/2491-iphone-6.html

That works fine, except for one thing.
When you click on "Aggiungi" (add to cart) does not come out from the pop-up, but redirects directly in the cart.

How can i solved this issue?
thank you!
