WooCommerce Product Add-Ons Display for Widget

I have installed:

1. WooCommerce
2. WooCommerce Bookings - http://ift.tt/1TBKynY
3. Products Add-Ons - http://ift.tt/1nOzs4H

For the default Products Add-Ons, it applicable to single-products page only. WooCommerce Bookings has included widget ready feature, in which I can drag and drop the widget into other pages. But for the other page, I can only use WooCommerce Booking without Products Add-Ons.

The example of the working well page as this: http://ift.tt/1SSF0XA

The problem is when I add the widget "Listify - Listing: Bookings", the Products Add-Ons below the booking form did not show. (I did not include the widget here, because the web is live) http://ift.tt/1nOzs4I

What if I wanted to apply the function into WooCommerce Bookings widget, so that I can drag and drop the widget wherever I wanted in future? With the functionalities of Products Add-Ons. Or any better idea for the implementation. Thanks!
