WPF - Binding Converted Enum To ComboBox

I tried to bind the following Enum to a ComboBox
Public Enum PossibleActions
ActionRead
ActionWrite
ActionVerify
End Enum

I can't change the Enum itself, but I do not want to display these strings. My intention is just to cut the prefix 'Action' and display 'Read', 'Write' and 'Verify' in the ComboBox.

Therefore I wrote a ValueConverter
Public Class PossibleActionsConverter
Implements IValueConverter
Public Function Convert(ByVal value As Object, ByVal targetType As System.Type, ByVal parameter As Object, ByVal culture As System.Globalization.CultureInfo) As Object Implements System.Windows.Data.IValueConverter.Convert
