Jquery not able to find checkbox ID or Name

I've got a page of checkbox that are styled. I'm trying to return their name or ID when they are changed.

I've created a fiddle here: http://ift.tt/29peJ1O

That shows the issue. The jquery I'm using is :

$(document).ready(function() {
    $(this).change(function() {
        alert($(this).attr("name"));
        alert($(this).attr("id"));
    });
});

Can anyone advise why this isn't working ?

Thanks
