Node JS and ajax problems

I am trying to receive data through ajax from node.js but I am not sure what I am doing wrong between interacting the two.

Here is my ajax get request:

$.get('/notificationsNumber',  
        function (notify) {
            alert(notify);
            $('.notifications').html("Notifications " + 0).css("color","red")

    });   

Here is my node.js file:

exports.notificationsNumber = function(req, res) {
    console.log('notifying start');
    Friend.findOne({userId: req.signedCookies.userid}, function(err,user) {
        if(err) {
            res.send(err);
            console.log('notifying err');
        } else {
            console.log('notifying');
            console.log(user.notifications);
            var notify = user.notifications;
            console.log(notify);
            res.send(notify);
        }
    });
};

UPDATE:

app.get('/notificationsNumber', user.notificationsNumber);

Here is the app.js code:

The alert is popping up the html doc of the page for some reason... and the line underneath it actually works correctly. Trying to connect the notify (which on the server side prints out the correct data).
