Buttons rapid-fire when exported/uploaded to Ouy

(I apologize if this is covered in another Android-related thread. New to this.)

I just put a prototype of a game I'm developing on my Ouya. It only uses two buttons. One function is to hit both buttons to shoot a small laser, and another involves holding both buttons to charge up for a more powerful shot. This works on my PC (using either the keyboard or gamepads), but when I used CocoonJS and threw the game on the Ouya any instance of holding both buttons caused them to rapid-fire.

Has anyone else had this problem? And, if so, is there a way to get around it?

Thanks.
