fb.login seems to cause page reload

Question

I'm using the javascript sdk for facebook. I have a my own site specific "like" button, but want to check if the user is logged in before sending the request to the server. I used the fb.login() function as follows but whenever it gets called the page the "like" button is refreshed. Why does it get refreshed?

        $('#like_id').click(function() {
        FB.getLoginStatus(function(response) {
            if (response.session) {
                // logged in and connected user, someone you know
                return true;
            } else {
                // no user session available, someone you dont know
                FB.login(function(response) {
                    if (response.session) {
                        return true;
                    } else {
                        return false;
                    }
                });
            }
        });
    });
