Bubbling phase and Lua system event

Hi
I would like to have both Scroll AND touch feature.
I’ve tried the ScrollView example and put a button inside the scrollView content, but the button doesn’t respond to a touch event.
With Adobe AS3, I will use the bubbling phase to manage this kind of problem.
Is it possible to do the same with Lua.
