[Plugin: SEO Facebook Comment] Comments Popup window

My comments are viewed by using comments_popup_window function.
Although Seo Facebook Comments plugin doesn’t show up inside the pop-up window.
I thought it was appended in the default comments system since it shows in a single post page.
How can I make it work inside the default comments pop_up window.
Here is the link. Please click on where it says $ Yorum.
