you need to query the code after certain interval which you can use AJAX to update the page without refresh. There is no automatic updates without query the information every time.

You have to subscribe using one module and you specify a callback url during the subscription... you only subscribe once and you get updates for everyone who has authorized your app. The updates come to you via the callback url and its very crappy info that basically tells you that you have to go back and query fb to get the full details.
