window.fbAsyncInit = function () {

    FB.Event.subscribe('edge.create', function (response) {
        alert('Liked');
        });
    }
    );
    FB.Event.subscribe('edge.remove', function (response) {
        alert('DisLiked')
    });
};

(function (d, s, id) {
    var js, fjs = d.getElementsByTagName(s)[0];
    if (d.getElementById(id))
        return;
    js = d.createElement(s);
    js.id = id;
    js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.7";
    fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
