Removing Note in JavaScript

I have a program that stores user's notes. When a user select the delete button, the program should remove the note. I have tried to use remove() but it does not change anything. The note is not being removed. Any suggestions on how to implement a remove button?

router.post('/delete/:id',function(req, res) {
    var username = req.session.username;
    var id = ObjectID(req.body.id);
    var noteTitle = req.body.title;
    var content = req.body.content;

    var resultsPage = function(status) {
    res.render("delete.jade", {title: status,
                    noteTitle: noteTitle});    
    }

    var checkUpdate = function(err, result) {
    if (err) {
        resultsPage("Update Failed");
    } else {
        resultsPage("Update Succeded");
    }
    }

    if (username) {
    notesCollection.remove({_id: id},
                   {$set: {title: noteTitle,
                       content: content}},
                   checkUpdate);
    } else {
    res.redirect("/?error=Not Logged In");
    }
});
