Custom Look for your Store - addToCart issue

Hi, I used a repeater with +/- quantity and using the addToCart function to have a custom store.
Problem is every time I call addToCart() I get redirected to the cart, which interrupts the buying behaviour - especially on mobile. It’s terrible in terms of user experience.
Do you have a solution on how to stay on the page when click addToCart button and only having the cart icon get updated ?

Many thanks,
Regards

Can I use something with onCartCreated( ) ?
