How do I cancel touch when curser/finger is outside of h5 game borders.

So its a problem I'm having with a few games, when the touch - either mouse or finger is outside of the h5 game border the game still keeps thinking its in touch.

what I want to do is either disable it when its outside( I cant check if its outside of layout since its outside of the game itself) or just stop the touch behavior from thinking its still "in touch".

thanks in advance!
