Facebook like button does not work for specific content type

I have facebook like button 7.x-2.3 installed on my drupal 7 site.
It works all fine for all content types except one despite of having that content type checked in the "Dynamic Like button settings".
The like button is displayed without any error in the content page.
When I press the like button, the button goes dimmed for few seconds saying that I've liked this page. However, after that the like button becomes enabled again and my like disappears saying that nobody has liked the page yet.
Does anyone know what could be the possible issue as the like button works fine for content types other than this one.
