Telerik GridViewSelectColumn - Map Checkbox To Boolean Property

(I've looked far and wide for a Q&A before asking, but please forgive if it's already around somewhere else and I missed it.)

I'm just trying to do something that seemingly should be simple... trying to map individual checkboxes in a telerik:GridViewSelectColumn in a telerik:RadGridView to a corresponding Boolean property of an entity mapped for each individual row.

<telerik:RadGridView x:Name="MyGridView" ItemsSource="{Binding MyGridViewItems, Mode=TwoWay}" SelectionMode="Extended" AutoGenerateColumns="False">    
    <telerik:RadGridView.Columns>
    <telerik:GridViewSelectColumn Name="MyCheckBoxColumn">
        <telerik:GridViewSelectColumn.CellTemplate>
        <DataTemplate>
            <CheckBox Command="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type telerik:GridViewDataControl}}, Path=DataContext.IncludeChangedCommand}" CommandParameter="{Binding}" IsChecked="{Binding MyBooleanProperty, Mode=TwoWay}" />
        </DataTemplate>
        </telerik:GridViewSelectColumn.CellTemplate>                                            
    </telerik:GridViewSelectColumn>

    .
    .
    .

    </telerik:RadGridView.Columns>
</telerik:RadGridView>

How do I map MyBooleanProperty to each individual checkbox?
