Express parameterized routing having first value as param

I am trying to use the following

app.route('/:userId/notes').get(notes.listByUserId);

But It doesn't works for me and instead jumps the middleware for route defined as

app.route('/users/:userId').get(users.read).put(users.update).delete(users.delete);
app.param('userId', users.findUserById);

Well, why am I doing this way ? Because I would like to keep my route like this for having user wise notes.

How can I achieve the same if it's possible?
