transitionEnd events firing more than once

[GeoTimber]

Hello

I noticed that in Chrome the transitionEnd events fire more than once though I can clearly you see tried to make it fire once.

      complete = function(element) {

        return element.one(transitionEnd, function() {
          return callback(element);
        });

Why does it fire more than once? i have no clue, and find it odd.

I had to make sure the callback only fired once bying add this to the callback

      callback = function(element) {
        if (settings.infinite === false) {
          element.callOnce=true;
          if (element.callOnce) {
              element.callOnce=false;
              element.off(transitionEnd);
          }
              removeClass(element);
        }
        if (typeof settings.callback === 'function') {
          return settings.callback.call(element);
        }
      };

Hope this helps someone, thanks for making and publishing this script!
