double load function jquery

Good evening everyone I have a question about two load function. I hope you can help me.

 $(document).ready(function() {
    $('#link').click(function () {
        $("#top_menu").load("menu.php");
        $("#content").load("content.php");
        return false;
    });
});

second load function doesn't work, I mean it is doesn't load content. what is wrong?
