What is trigger “liszt:updated” in jQuery?

Question

I was following the answer here: Jquery's Chosen plugin with Chained plugin and select box

And I found a line that I just don\'t follow - as I don\'t understand

Answer 1

liszt:updated is just a custom event that Chosen was using at the time. It is not a standard event, so you won't find anything on the web about it.

Moreover, Chosen itself doesn't use that event name any more (they're using chosen:updated now ), which would make it even more difficult to find any references to it.

See here: How do I reset a jquery-chosen select option with jQuery?.
