Facebook Connect FB.getLoginStatus issues ~ JS SDK

I am having trouble executing the FB.getLoginStatus() method directly. When a user clicks the action button, I call the FB.getLoginStatus() however, this returns "Undefined". When I reload the page FB.getLoginStatus() works how it should. How can I get use of the FB.getLoginStatus() on demand with in the page. I have attached my source code.

The Function _checkFBStatus() calls the FB.getLoginStatus() when the user clicks the action button.

This click event is where everything takes place. I had to implement a hack in order to get this to work. Once the FB.login callback executes I redirect to the same page and call FB.getLoginStatus(). I would rather not use this hack:

        $('ul.fb')
            .click( function( event )
            {
                if( _checkFBStatus() )
                {
                    _getFriends();

                }else
                {
                    _login();   

                }   
            }
        );

Here is the full souce code:

        e.src       = document.location.protocol + '//connect.facebook.net/en_US/all.js';
        e.async     = true;

Is there any reason you don't use the response from the FB.login? It should contain the same connected info as calling FB.getLoginStatus.
