Button Bounce on PropertyChange - wpf

Question

I have a simple button (3 of them - all same except the content binding which is just an integer.
<Button Width="24" Height="24" Style="{StaticResource CircleButton}"
Background="#CC2B2B" Foreground="#FFFFFF"
Content="{Binding PinnedItemsCount,
FallbackValue=0,
Mode=TwoWay,
UpdateSourceTrigger=PropertyChanged,
NotifyOnTargetUpdated=True}"
Name="ui_btnPinnedCount" />
How do I make the button boune when the data changes?
The underlying content implements INotifyPropertyChanged and the data bindings are all working, just need the button to bounce 3 times once the data changes....
Thanks!

This makes it fade in and out, replace with any sotryboard animation I imagine.
<Button Width="24" Height="24" Style="{StaticResource CircleButton}" Background="#CC2B2B" Foreground="#FFFFFF"
Content="{Binding PinnedCount, FallbackValue=0, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, NotifyOnTargetUpdated=True}"
Name="ui_btnPinnedCount">
<Button.Triggers>
<EventTrigger RoutedEvent="Binding.TargetUpdated">
<BeginStoryboard>
<Storyboard AutoReverse="True">
<DoubleAnimation Storyboard.TargetName="ui_btnPinnedCount" Storyboard.TargetProperty="Opacity" To=".1" Duration="0:0:.5" />
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</Button.Triggers>
</Button>
