Flash GridControl Cell on value changed?

I have a simple DXGrid control with an obervable collection as its ItemsSource. The Items implemenet INotifiyPropertyChanged and are updated every two seconds with new integer values.

I'm trying to make a cell of the DXGrid flash with a ColorAnimation when it's vallues is updated without hacking the code-behind (following the MVVM principle).

C#
<Window x:Class="WpfApplication1.MainWindow"  
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"  
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"  
        xmlns:dxg="http://schemas.devexpress.com/winfx/2008/xaml/grid"  
        Title="MainWindow" Height="350" Width="525">  
    <Window.Resources>  
        <Style TargetType="{x:Type dxg:CellContentPresenter}" x:Key="MyStyle">  
            <Setter Property="Background">  
                <Setter.Value>  
                    <SolidColorBrush Color="Transparent"/>  
                </Setter.Value>  
            </Setter>  
            <Style.Triggers>  
                <EventTrigger RoutedEvent="Binding.TargetUpdated">  
                    <BeginStoryboard HandoffBehavior="Compose">  
                        <Storyboard>  
                            <ColorAnimation Storyboard.TargetProperty="(Background).(SolidColorBrush.Color)"  
                                                Duration="00:00:01"  
                                                AutoReverse="True"  
                                                From="Transparent" To="Yellow" />  
                        </Storyboard>  
                    </BeginStoryboard>  
                </EventTrigger>  
            </Style.Triggers>  
        </Style>  
    </Window.Resources>  
    <Grid>  
        <Button Width="90" Height="30" Name="button1" Click="button1_Click" Margin="5" VerticalAlignment="Top"/>  
        <dxg:GridControl Name="dataGrid1" ItemsSource="{Binding Values}"  
                  VerticalAlignment="Stretch" HorizontalAlignment="Stretch">  
            <dxg:GridControl.Columns>  
                <dxg:GridColumn Header="Value" DisplayMemberBinding="{Binding Value, Mode=OneWay, NotifyOnTargetUpdated=True}" CellStyle="{StaticResource MyStyle}"/>  
                <dxg:GridColumn Header="Value 1" DisplayMemberBinding="{Binding Value1, NotifyOnTargetUpdated=True}" CellStyle="{StaticResource MyStyle}"/>  
            </dxg:GridControl.Columns>  
        </dxg:GridControl>  
    </Grid>  
</Window>  

If I changed the RoutedEvent to MouseEnter the animation is triggered so I think the OnTargetUpdate event is getting lost.

Is there a solution using this methodology?

Thanks!
