[jQuery] 1.3 live doesn't seem to work with UI?

[Clumsy Hamster]

I have this bit of test code:

$('input').live('click',function(){
        $(this).datePicker();
});

But every time I run it, it always gives the message of "Object
doesn't support this method."  I've tried putting it onto a class
(.input), an ID (#input) and just a plain input with all the same
results.  Followed the instructions on the page 
http://docs.jquery.com/Events/live#typefn.

So, it is looking like either I'm doing something incorrectly or it
doesn't work with the JQuery UI.  Anyone see or know what may be
wrong?

thanks ^.^
