How to define InputBindings for RadDocking

[Sherry]

Hi,

In my code I have an defined at the Window level which then floats a pane, now I want to make the floated pane to be docked again using a shortcut key while the focus is on the floating RadPane.

I added this

 <telerik:RadDocking.InputBindings>
            <KeyBinding Gesture="Ctrl+D"
                        Command="{Binding FloatPanesCommand}" />
        </telerik:RadDocking.InputBindings>

 

But this does not work and the command is never triggered. Could someone please help.
