Datepicker events can't be bound

[be.davestein]

I saw a few bugs in regards to events not being fired when switching between pickers, but nothing like this so I don't think I'm submitting a duplicate.

Anyway I just did a long overdue upgrade of jquery from 1.4.2 and 1.8.11 to the latest of both. Now my old code of $('#el').bind('onSelect', function() { ... }) doesn't work.

As documented (see ​http://docs.jquery.com/UI/Datepicker#event-onSelect ) the Datepicker's onSelect event can only be handled by setting the onSelect option to a callback function. Most Datepicker events don't support binding through .bind() as do all the other widgets. Compare to something like ​http://docs.jquery.com/UI/Accordion#event-change. The exception is the one event provided by the widget factory, create ​http://docs.jquery.com/UI/Datepicker#event-create. The reason for this is that historically Datepicker wasn't build on top of the widget factory. It has been refactored to use some of the widget factory but not all of it. This will be supported by a complete rewrite of the Datepicker, which is underway ( see #6737 and #6228 ). The existing code is only being modified to address critical issues and regressions.

seems to suggest you find this behavior a regression since jQuery 1.4.2 and jQuery UI 1.8.11 but the behavior is the same with those versions. See ​http://jsfiddle.net/x2LFH/4/
