Button Click event won't fire in WP8 - xaml

Question

I have a layout like this.
<Grid Grid.Row="4" HorizontalAlignment="Stretch" VerticalAlignment="Bottom" Name="gridTestAd" Height="80" Margin="-12,0,-12,0" >
<StackPanel Orientation="Vertical" Tap="StackPanel_Tap">
<StackPanel.Background>
<ImageBrush ImageSource="/Assets/image.jpg" />
</StackPanel.Background>
</StackPanel>
<adduplex:AdControl x:Name="adDuplexAd" AppId="123456"/>
<Button Name="btnRemoveAd" Content="X" Height="40" Width="40" HorizontalAlignment="Right" VerticalAlignment="Top" Background="Red" BorderBrush="Red" Foreground="White" Template="{StaticResource RemoveAdsButtonStyle}" Margin="0,-20,6,0" Click="btnRemoveAd_Click" />
</Grid>
I have set a breakpointin the btnRemoveAd_Click event but when i tap the button, the click event will not fire. Originally i created a custom button using images but that did not work either. This button is slightly edited using Blend because its so small and content is not showing. But only changes to Margin of the original button. I have search for the reasons but did not find any and i cant figure it either. What may be the problem? Please help
