to bind this event to the text box in question,

$(document).ready(function() {

  //your code above here.....

  $("#TagsTextBox").keyup(function(event){
     if(event.keyCode == 32)
     {
         $("#TagsTextBox").autocomplete('search', $("#TagsTextBox").val());
     }
  });
});

hopefully that at least puts you on the right track.
