Facebook like button not works correctly in CanJS(single page) web application.

I wanted to put like button in my web application.

Then I followed facebook Like button page. https://developers.facebook.com/docs/plugins/like-button

At the first time, the Like button not showed up correctly but it shows well after putting codes below.

FB.XFBML.parse();

When I click the Like button, Facebook can not get right information of the page.

I've already put meta tags(og:title, og:description) before Like button parsed.

How can I figure out this problem?

The Share buttons works great because I use FB.ui for the Share button.
