How do I increment a value server side nested in an array using Node, MongoDB and Mongoose?

I am trying to create a route that will update a specific value in an object in a nested array. I am getting a 404 error in my node console. I am almost certain that this is not the way to do it but my code will give an idea of what I want to achieve:

router.put('/getProfile/:profile_id/addWin'), function (req, res) {
UserProfile.findOne({
    UserID : req.params.profile_id //Find the correct Profile
}, function (err, profile) {
    if (err)
        res.send(err);

    profile.Drafts.findByID({ //Find the corrct Draft in the Profile
        _id : req.body.DraftID
    }, function (err, draft) {

        if (err)
            res.send(err);

        draft.Wins += 1; //Increment the wins
    })

    profile.save(function (err) { //Save the profile
        if (err)
            res.send(err);

        res.json({
            message : 'Win added!'
        });
    });
});}

this is the error in the console:

PUT /api/getProfile/575ecce6924295bc21000005/addWin 404 5.128 ms - -

The route should find the correct profile (this works in my other routes), using the profile_id, then access the Drafts array and find the correct Draft and increment the wins. How do I achieve this?

In my request body I just send the DraftID and the profileID as parameter and is stored in a UserID property in the profile object.

This is my first attempt ever at the MEAN stack so I am not comfortable yet.
