jquery UI Combobox ONCHANGE

how can I attach an onchange function in a jqueryUI combobox? Here is my code:

$(".cmbBox").combobox({
     change:function(){
         alert($(this).val());
     }
});

When the value changes, it will alert the updated value.

Any help please.. :)

The combobox example source is all right there in the example. I'd trigger the change event of the underlying select by modifying the source code like this (changing the select event handler inside autocomplete initialization inside the plugin):

/* Snip */
select: function( event, ui ) {
    ui.item.option.selected = true;
    self._trigger( "selected", event, {
        item: ui.item.option
    });
    select.trigger("change");                            
},
/* Snip */

and then define an event handler for the regular change event of the select:

$(".cmbBox").change(function() {
    alert(this.value);
});

Unfortunately this won't work exactly the same way as the normal select.change event: it will trigger even you select the same item from the combobox.
