The problem presents itself here:
http://docs.angularjs.org/api/ngTouch/directive/ngSwipeLeft

I cant seem to click and drag the demo text to reveal the 'reply' and 'delete' button.
Also using chromes 'emulate touch' does not work.
Also swiping the text on my iPhone 4s iOS7 does not work.

It's hard to believe there can be something wrong with that part of the code as it must be core to many apps, but i cant seem to get it working :s

is the demo page complete?
