When I pass a little complex DOM query to $._data like this: $._data($('#outerWrap .innerWrap ul li:last a'), 'events')
it throws undefined in the browser console.
So I had to use $._data on the parent div: $._data($('#outerWrap')[0], 'events')
to see the events for the a tags. Here is a JSFiddle for the same: http://jsfiddle.net/giri_jeedigunta/MLcpT/4/
