Custom CheckBox in WPF DataGrid does not update binding

Question

I have the following (simplified) style:

<Style x:Key="MyStyle" TargetType="{x:Type CheckBox}">  
    <Setter Property="Background" Value="Blue" />  
</Style>

If I use it as the ElementStyle AND EditingElementStyle in my DataGridCheckBoxColumn:

<DataGridCheckBoxColumn Binding="{Binding IsEnabled}"  
                        ElementStyle="{StaticResource MyStyle}"  
                        EditingElementStyle="{StaticResource MyStyle}" />

Then my binding, IsEnabled, does not toggle when I check/uncheck a row's checkbox. If I remove either ElementStyle, EditingElementStyle, or both, then the binding updates no problem. Why is this?!

Also, I tried to work around the problem using the following code:

<DataGridTemplateColumn>
    <DataGridTemplateColumn.CellTemplate>
        <DataTemplate>
            <CheckBox IsChecked="{Binding IsEnabled}"/>
        </DataTemplate>
    </DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>

However, the problem remains.

Sorry for the necro, but I think I found a better solution here on Stack Overflow that might help people ending up on this page searching for a solution.

<DataGridTemplateColumn.CellTemplate>
    <DataTemplate>
        <CheckBox IsChecked="{Binding Path=IsSelected, UpdateSourceTrigger=PropertyChanged}" />
    </DataTemplate>
</DataGridTemplateColumn.CellTemplate>

I tried this and it worked perfectly for me, simpler than the accepted solution and also eliminating the need for extra clicks on the checkboxes.
