Detect Tap on CalloutBubble in MKAnnotationView

Im working with MKMapView and MKAnnotationView.

I have an annotation in the map. When the users tap on it, the callOut Bubble is displayed. When the annotation is tapped again ( and the callOut Bubble is visible ) i need to change to another view.

How can i detect the second tap, or the tap in the bubble?

Could you add a gesture recognizer when you're initializing the MKAnnotationView?

Here's the code for inside dequeueReusableAnnotationViewWithIdentifier:

UITapGestureRecognizer *tapGesture = 
        [[UITapGestureRecognizer alloc] initWithTarget:self 
[theAnnotationView addGestureRecognizer:tapGesture];
[tapGesture release];

The method for the gesture recognizer:

-(void) calloutTapped:(id) sender { 
    // code to  display whatever is required next.

    // To get the annotation associated with the callout that caused this event:
    // id<MKAnnotation> annotation = ((MKAnnotationView*)sender.view).annotation;
