javascript event for a mobile pinch/zoom action

I need some help. I am trying to work on a mobile web page. What i'm trying to do is "capture" when the user does a zoom in/zoom out action. That is, when they put two fingers on screen and separate or close their fingers together. I looked at jquery mobile and didn't see it.

So specifically can I attach a javascript function to a pinch/zoom event in a mobile device?

Any help would be greatly appreciated.

Touchy is a jQuery plugin that provides support for pinch, drag, swipe, longpress, rotate. It works on any browser that implements touchstart, touchmove and touchend. Future versions will also support IE10.

Zepto is a jquery compatible library for mobile and provides handlers for pinch events. Unfortunately, they are listed as iOS only. (See "Touch Events")

Synopsis:

$('some selector').pinch(function(){ ... });
$('some selector').pinchIn(function(){ ... });
$('some selector').pinchOut(function(){ ... });
