How to force a TextChanged event on a WPF TextBox and mantain the focus?

Question

I am creating a numeric TextBox in WPF, with two buttons to increase and decrease the value.

I have create two RoutedCommand to manage the behiavor and they are working well. There is only one problem that I would like to solve. I would like that the control notifies all object binded to its TextProperty when an increase or decrease command is executed.

At the moment it sends the notification only when I change the focus to another control

Any help is really appreciated, Thank you

There is a simple way:

Text="{Binding Path=MyProperty, UpdateSourceTrigger=PropertyChanged}"

(I tested it on TextBox). Good Luck
