Autocomplete events (.change) not firing

Autocomplete events (.change) not firing

 
Hello.
 
I am using the follow Autocomplete code on a textbox in my web page, and it is working well except for the events not firing.
 
I've tried change, selected, and a few others with no success.  Can anyone tell me what I'm missing?
 
 
<
script type ="text/javascript">
$(document).ready( function () {
$( '#tbOrganization' ).autocomplete( '@ Url.Action( "LookupOrgs" , "Utilities" ) ' , {
dataType: 'json' ,
parse: function (data) {
var rows = new Array();
for ( var i = 0; i < data.length; i++) {
rows[i] = { data: data[i], value: data[i].Tag, result: data[i].Tag };
}
return rows;
},
formatItem: function (row, i, max) {
return row.Tag;
},
change: function (event, ui) {
      alert( 'hi' );
},
width: 300
});
});
</ script >
