WPF: instances of sharecontrol usercontrol dependency properties

Question

I created a usercontrol and it works fine, but when I put two instances of this control in one window, only the last one works. I tried to find a solution, and I realized that dependency properties are common, but I don't know how to make it work.

Here is my dependency property:

    public double AnimatingVerticalOffset
    {
        get { return (double)GetValue(AnimatingVerticalOffsetProperty); }
        set { SetValue(AnimatingVerticalOffsetProperty, value); }
    }

    public static readonly DependencyProperty AnimatingVerticalOffsetProperty;

    static ListChooser()
    {
        ListChooser.AnimatingVerticalOffsetProperty =
                   DependencyProperty.Register("AnimatingVerticalOffset", typeof(double), typeof(ListChooser), new UIPropertyMetadata(OnAnimationVerticalOffsetChanged));
    }

public static readonly DependencyProperty AnimatingVerticalOffsetProperty =
               DependencyProperty.Register("AnimatingVerticalOffset", typeof(double), typeof(ListChooser), new UIPropertyMetadata(OnAnimationVerticalOffsetChanged));

static ListChooser()
