How to increment by one on a click?

I'm trying to add in an increment/decrement by one component like the one below, but having a hard time figuring out how to do this in Bravo. The use case would be someone has added multiple items to a shopping cart and then wants to change the quantity for each row by pressing the plus or minus button the adjust the quantity by one before checking out. I know this could be accomplished by using a text field or drop down to update, but would prefer to use the button increment.

Thank you for your help!
