I was following these example : http://jsfiddle.net/Shef/k6TEZ/ , in which is used the callback show(). I am executing this callback too
callback
show()
According to the jQuery UI 1.9 changelog:
Deprecated: show event; renamed to activate.
And according to the jQuery UI 1.10 changelog:
Removed: show event.
Looks like you should use either activate or beforeActivate.
