How to listen to a BindingBase object?

Hi

I want to create a special DataTrigger inheriting the TriggerBase<FrameworkElement>. Just similar to theDataTrigger, a property of type BindingBase has been defined in theMyDataTrigger class. 

How can I listen to it in order to trace its changes?

    public class MyDataTrigger : TriggerBase<FrameworkElement>
    {
        ...

        /// <summary>
        /// [Wrapper property for BindingProperty]
        /// <para>
        /// Gets or sets the binding that produces the
        /// property value of the data object.
        /// </para>
        /// </summary>
        public BindingBase Binding
        {
            get { return (BindingBase)GetValue(BindingProperty); }
            set { SetValue(BindingProperty, value); }
        }

        public static readonly DependencyProperty BindingProperty =
            DependencyProperty.Register("Binding",
                                        typeof(BindingBase),
                                        typeof(MyDataTrigger),
                                        new FrameworkPropertyMetadata(null));

    }

More Info:

The main problem is that I don't know how to find the BindingBase associatedDependencyProperty. I know how to listen to a DP;

void ListenToDP(object component, DependencyProperty dp)
{
    DependencyPropertyDescriptor dpDescriptor = DependencyPropertyDescriptor.FromProperty(dp, component.GetType());
    dpDescriptor.AddValueChanged(component, DPListener_ValueChanged);
}

Where DPListener_ValueChanged is an EventHandler delegate. Here, thecomponent parameter value is this.AssociatedObject.
