i just working with Wikitude and Google maps in AngularJS(Ionic). I need to set ng-click event for InfoWindow in my controller. My code:

```
google.maps.event.addListenerOnce($scope.map, 'idle', function(){

  var marker = new google.maps.Marker({
      map: $scope.map,
      animation: google.maps.Animation.DROP,
      position: latLng
  });

  var infoWindow = new google.maps.InfoWindow({
      content: '<a href="#" ng-click="launchAR(\'my_world_pls\')">CATCH!</a>'
  });

  google.maps.event.addListener(marker, 'click', function () {
      infoWindow.open($scope.map, marker);
  });

});

```
