Late reply but might help someone!

Considering the two events in autocomplete widget

1) change - triggered when field is blurred and value is changed.

2) response - triggered when the search completes and the menu is shown.

Modify the change and response events as follows:

change : function(event,ui)
{  
if(!ui.item){
$("selector").val("");
}
},

response : function(event,ui){
if(ui.content.length==0){
  $("selector").val("");
}
}

Hope this helps!
