Trying to use ItemsControl.AlternationIndex to show row index in list

I've got the following XAML which is intended to put the row number in the left column but all that gets output is 0

<ListBox 
VirtualizingPanel.VirtualizationMode="Recycling"
ItemsSource="{Binding MoineauPumpFlanks.Stator.Flank.Boundary, Mode=OneWay}"
   AlternationCount="2147483647"
   >
   <ListBox.ItemTemplate>
       <DataTemplate>
           <StackPanel Orientation="Horizontal">
               <TextBlock 
                   Text="{Binding RelativeSource={RelativeSource Mode=Self}, 
                                  Path=(ItemsControl.AlternationIndex)}"
                   Margin="0,0,5,0"
                   />

                <!-- A custom control of mine -->
               <Controls:LabelForPoint Point="{Binding}" />
           </StackPanel>
       </DataTemplate>
   </ListBox.ItemTemplate>
</ListBox>

Can anybody suggest what is wrong here?

The below does what I want

<TextBlock Text="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, 
           Path=TemplatedParent.(ItemsControl.AlternationIndex)}"
    Margin="0,0,5,0"
    />
