On [line 15](https://github.com/shwing/chosen/blob/54c26df052292a86b55a6b19de961a7ed8ccc164/coffee/chosen.jquery.coffee#L515) `liszt:updated` is triggered, so the change event should, if needed, be triggered there and not here. Also if using a ajax handler for the option adding, the option is not added at this point, so the select won't be changed. And, correct me if I am wrong, when the option is added the select's change event is already triggered.
