[jQuery] close event on dialog ?

[Maskime]

Hi everyone,

I have ugraded JQuery to v1.3.2
But since i did that it looks like i've lost the close event on
dialogs
I've trying this :
$('#dialog').dialog({close : function(){alert("lorem");}});

but when i click on the 'X' of the dialog nothing happens...

Any idea where it could come from ?
