Swipe gestures on a mobile scroller

I have a native mobile scroller handling the vertical scroll of a field. 
I want to add swipe gestures to change cards. When swiping, I get a 
mouseDown, sporadic mouseMoves (the logging might be interfering, not 
sure, but after a couple they stop) and no mouseUp at all.

I tried using touchStart/touchMove/touchEnd instead and the result is 
the same. TouchStart always fires, touchMove is iffy, and touchEnd never 
happens.

Without the end message I can't calculate the direction. Plain taps work 
fine with either set of messages, I do get mouseUp/touchEnd if it's a 
tap. It's only swipes that don't report.

The scroller has its hScroll property set to false if that matters, as I 
don't want horizontal scrolling but I do want to track the touch direction.
