This is my user control code

Mainwindow as shown there are two buttons, I test points in the first button, first come out the value of more than seven hundred and 0, the second button and then points the first button is still the same,
However I manually add the xaml data binding and then test point out the first button is the same two values,
Why is this? Not science! Big help genuflect is begged! In this for several hours almost doubt life!
