Detail disclosure button not appearing on mapkit callout

I'm not sure why the detail disclosure button is not appearing on the mapkit callout. Here's my code:

I made sure to include in the .h file and then the following methods. The callout works and appears right after the map loads. I also made sure to hook up the delegate in the Xib file.

   - (MKAnnotationView *)mapView:(MKMapView *)map viewForAnnotation:(id <MKAnnotation>)annotation
{
    MKPinAnnotationView *mapPin = nil;
    if(annotation != map.userLocation) 
    {
        static NSString *defaultPinID = @"defaultPin";
        mapPin = (MKPinAnnotationView *)[map dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
        if (mapPin == nil )
        {
            mapPin = [[MKPinAnnotationView alloc] initWithAnnotation:annotation 
                                                     reuseIdentifier:defaultPinID];
            mapPin.canShowCallout = YES;

            UIButton *disclosureButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
            [disclosureButton addTarget:self action:@selector(clDetails:) forControlEvents:UIControlEventTouchUpInside];

            mapPin.rightCalloutAccessoryView = disclosureButton;

        }
        else
            mapPin.annotation = annotation;

    }
    return mapPin;
}




  - (void)mapView:(MKMapView *)mapView didAddAnnotationViews:(NSArray *)views
{
    id<MKAnnotation> myAnnotation = [self.mapView.annotations objectAtIndex:0];
    [self.mapView selectAnnotation:myAnnotation animated:YES];
}

thanks for any help.

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation

{ // if it's the user location, just return nil. if ([annotation isKindOfClass:[MKUserLocation class]]) return nil;

// try to dequeue an existing pin view first
static NSString* AnnotationIdentifier = @"AnnotationIdentifier";
MKPinAnnotationView* pinView = [[[MKPinAnnotationView alloc]
                                 initWithAnnotation:annotation reuseIdentifier:AnnotationIdentifier] autorelease];
pinView.animatesDrop = YES;
pinView.canShowCallout = YES;
pinView.draggable = NO;
pinView.annotation = annotation;
pinView.draggable = YES;
pinView.enabled = YES;
pinView.exclusiveTouch = YES;
pinView.highlighted = YES;
pinView.multipleTouchEnabled = YES;
pinView.pinColor = MKPinAnnotationColorPurple;
pinView.userInteractionEnabled = YES;

//button on the right for popup for pins
UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[rightButton setTitle:annotation.title forState:UIControlStateNormal];
[rightButton addTarget:self
                action:@selector(showDetails:)
      forControlEvents:UIControlEventTouchUpInside];
pinView.rightCalloutAccessoryView = rightButton;


 //Create and add the right button to the callout
 rightCalloutButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[pinView setRightCalloutAccessoryView:rightButton];

    [self updateAnnotation];

    [self crawlViews];

//zoom button on the left of popup for pins
UIButton* leftButton = [UIButton buttonWithType:UIButtonTypeContactAdd];
[leftButton setTitle:annotation.title forState:UIControlStateNormal];
[leftButton addTarget:self 
               action:@selector(zoomToLocation:) forControlEvents:UIControlEventTouchUpInside];
pinView.leftCalloutAccessoryView = leftButton;

UIImageView *profileIconView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"profile.png"]];
pinView.leftCalloutAccessoryView = profileIconView;
[profileIconView release];

return pinView;

I had this line of code in viewDidLoad that was throwing off the MKAnnotation method.

mapView = [[MKMapView alloc]initWithFrame:self.view.bounds];

:)
