CancelActive.excute does not work

I am working with a custom version of the Cut command on the editor widget and I cannot get it to deactivate:

Dim editor As Editor = TryCast(LayoutRoot.Resources("SplitEditor"), Editor)
If Not editor Is Nothing Then
If editor.CancelActive.CanExecute(nothing) Then <--- This is never True
editor.CancelActive.Execute(nothing) <--- This never fires
End If
End If

'--- XAML
<Button x:Name="btnSplitStreet" Style="{StaticResource MenuButton}"
ToolTipService.ToolTip="Split Street" Command="{Binding Cut}" Click="btnSplitStreet_Click">

<esri:Editor x:Key="SplitEditor" EditCompleted="EditorWidgetSplit_EditCompleted"
Map="{Binding ElementName=Map}"
LayerIDs="GPS, Roads"
GeometryServiceUrl="http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer" />

Is your Button DataContext set to the Editor? Also, if you have Command set to Cut, you don't have to do anything extra in the Click event. Activating a command, deactivates current active command. You can also wire up to Editor.EditorActivated event to check that a command becomes active when you click the button for cut.

I think I figured it out. It looks like I was trying to deactivate it before it was active. I got it working now.
