Is there any way to get the count of Likes and Share for specific post on users timeline using graph api?

I tried with one of available endpoint in documentation like below

http://ift.tt/1DGtQAh] or [post-id]/likes?summary=true

But it returns always summary count zero even there is like and share shown facebook platform .

"summary": { "total_count": 0

could anyone please provide the answer me on this ?
