I’m using html/javascript with iOS and UIWebView. I want to invoke an objective-c method

I’m using html/javascript with iOS and UIWebView.
I want to invoke an objective-c method when the user touch anywhere on the page that isn’t a link.

At the moment I have

...

<BODY ontouchend="bodyTouch();">
<HEAD>
    <script language="javascript" type="text/javascript">
        function bodyTouch() {
            invokeObjectiveC();
            }
        }
     </script> 

...
<DIV id=buttons>
<A id=navigator href="CustomScheme:SomeAction"></A>
....

How can I set things up so that bodyTouch() only gets invoked if the user touches anywhere on the screen that isn’t a link/button/anchor etc.

==== Update ===

Thanks for lots of answers folks.
Unfortunatly I couldn’t get any of them to work (now my InvokeObjectiveC() doesn’t get called at all when I try any of them).
I’m an iOS developer and don’t know html/javascript. I’ll do a bit of studying as I don’t understand any of the answers at the moment with my limited knowledge, then try them once I understand what they are doing and try to figure out why its not working.
I’ll mark one of the answers as accepted in due course.
Cheers

    give this one a shot, you should be able to place this anywhere in the document

    <script>
document.addEventListener('DOMContentLoaded', function () {
 document.documentElement.addEventListener('click', function (e) {

  /* CHECK IF THE TARGET IS IN YOUR BANLIST */
  if (['A', 'BUTTON'].indexOf(e.target.tagName) === -1) {

   /* I WOULD CALL THESE FOR GOOD MEASURE */
   e.preventDefault();
   e.stopPropagation();

   /* THIS IS YOUR FUNCTION */
   invokeObjectiveC();
  }
 }, true);
}, false);
</script>

    this does not work on the input[type=button] looking buttons, if you need that as well let me know
