You can certainly use a decorator to add functionnality. I've made a quick plunkr to demonstrate how. Basicaly, in your decorator body, you replace the compile function with your own for your custom logic (in the example, binding to the click event if the track attribute is present) and then call the original compile function. Here's the snippet:

$provide.decorator('ngClickDirective', function($delegate) {
  var original = $delegate[0].compile;
  $delegate[0].compile = function(element, attrs, transclude) {
    if(attrs.track !== undefined) {
      element.bind('click', function() {
        console.log('Tracking this');
      });
    }
    return original(element, attrs, transclude);
  };
  return $delegate;
})
