Using Completed event for "ImeAction.Search"

I've successfully created a custom renderer "SearchEntry" to enable the "Search" button on the keyboard for this entry.
I'm also using the Completed event on the entry. On iOS this event gets fired, but not on Android.
When I look into the code of the EntryRenderer on Android, the Completed will not be fired when the ImeAction is "Search", see:

bool TextView.IOnEditorActionListener.OnEditorAction (TextView v, ImeAction actionId, KeyEvent e)
{
    if (actionId == ImeAction.Done || (actionId == ImeAction.ImeNull && e.KeyCode == Keycode.Enter)) {
        base.Control.ClearFocus ();
        v.HideKeyboard (false);
        base.Element.SendCompleted ();
    }
    return true;
}

Thanks!
