WP7 Popup not showing - windows-phone-7

Question

In my app I want to display a simple string within a popup when the user clicks on an image. For this I added a Tap gesture listener to the image and within the handler I have the following code:
private void GestureListener_Tap( object sender, GestureEventArgs e )
{
var img = sender as Image;
if( img == null ) {
return;
}
Point pos = e.GetPosition( img );
string text = "I'm a popup!";
var popup = new Popup() {
Child = new Border() {
BorderBrush = new SolidColorBrush( Colors.LightGray ),
Child = new TextBlock() {
Text = text,
TextWrapping = TextWrapping.Wrap,
},
},
HorizontalAlignment = HorizontalAlignment.Stretch,
HorizontalOffset = pos.X,
VerticalOffset = pos.Y,
Visibility = Visibility.Visible,
};
popup.IsOpen = true;
Debug.WriteLine( "GestureListener_Tap: " + text );
}
The call to WriteLine prints in the debugger output window but the popup doesn't get displayed. What am I doing wrong here?
Thanks for your help!

I tried your code and the Popup is displayed. I think the problem for you is the Position for the Image relative to the Mouse. Try to set another Background for the Parent Container and I think you'll see the Popup. You can also try to play around with
Point pos = e.GetPosition(null);
until you get the Position you require
