GestureRecognizer is not working on android using Xamarin.forms

public void EnableSubmitButton(){
LeftMenuItem.IsEnabled = true;
TapGestureRecognizer OnLeftMenuItemClicked = new TapGestureRecognizer ((s,e) => {
OnSubmitClicked (s,e);
});
LeftMenuItem.GestureRecognizers.Add (OnLeftMenuItemClicked);
}

This is the code which is used to add gesture recognizer into the Image. It's working on iOS perfectly. But In android OnLeftMenuItemClicKed is not triggered.

Thanks in Advance.
