Pressed and released event doesn't get triggered?

[gunnicus]

Here is my code:
<controls:CircleButton Image="playstationcross_70x70.png" HorizontalOptions="Center" Grid.Row="3" Grid.ColumnSpan="3" HeightRequest="70" BorderRadius="70" WidthRequest="70" BorderColor="Black" BackgroundColor="Black" Clicked="CrossButton_Clicked" Pressed="CrossButton_Pressed" Released="CrossButton_Released"

I added CrossButton_Pressed and CrossButton_Released but those 2 event never got triggered when I press the button.
