如何将IsEnabledChanged (非路由事件)路由到EventHandler WPF

public static class IsEnabledChangedHelper
{
    public static readonly DependencyProperty IsEnabledChangedProperty =
        DependencyProperty.RegisterAttached("IsEnabledChanged", typeof(EventHandler), typeof(IsEnabledChangedHelper),
            new PropertyMetadata(null, OnIsEnabledChanged));

    public static void SetIsEnabledChanged(DependencyObject element, EventHandler value)
    {
        element.SetValue(IsEnabledChangedProperty, value);
    }

    public static EventHandler GetIsEnabledChanged(DependencyObject element)
    {
        return (EventHandler)element.GetValue(IsEnabledChangedProperty);
    }

    private static void OnIsEnabledChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var element = (UIElement)d;
        var handler = (EventHandler)e.NewValue;

        if (handler != null)
        {
            element.IsEnabledChanged += handler;
        }
        else
        {
            element.IsEnabledChanged -= handler;
        }
    }
}

<Button Content="Click Me" local:IsEnabledChangedHelper.IsEnabledChanged="{Binding IsEnabledChangedHandler}" />
