 ## How can I mimic a native browser event, if not `.trigger()`?
 
 In order to trigger a native browser event, you have to use [document.createEventObject](http://msdn.microsoft.com/en-us/library/ie/ms536390%28v=vs.85%29.aspx) for < IE9 and  [document.createEvent](https://developer.mozilla.org/en/DOM/document.createEvent) for all other browsers.

 1. `.triggerHandler()` only triggers the event on the first element of a jQuery object.
 2. `.triggerHandler()` cannot be chained. It returns the value that is returned by the last handler, not a jQuery object.
 3. `.triggerHandler()` will not cause the default behavior of the event (such as a form submission).
-4. Events triggered by `.triggerHandler()`, will not bubble up the DOM heirarchy. Only the handlers on the single element will fire.
