iOS Question [B4XPages] - how to handle KeyboardStateChanged event

[Alexander Stolte]

How can i handle the "KeyboardStateChanged" Event with B4XPages?
This is not raising:

Private Sub Page1_KeyboardStateChanged (Height As Float)
    Log("Page1_KeyboardStateChanged: " & Height)
End Sub

Replace Page1_ to B4XPage_
