Node.js wont read my function

Hi Guys

Im stuck in a node.js script where I have a function that doesnt work, I Feel I have tried everything.

    // load up the user model
var User = require('../app/models/user');
// auth.js
module.exports = {
    // route middleware to make sure
    isLoggedIn: function (req, res, next) {
        // if user is authenticated in the session, carry on
        if (req.isAuthenticated())
            return next();
            //next(); 


        else {
            // if they aren't redirect them to the home page
            res.redirect('/');
        }
    },

    isInCompany: function(req, res, next) {
        module.exports.isLoggedIn,
        function (req, res, next) {



           return next();
        }
    },

As you can see my problem is that this doesnt work :

isInCompany: function(req, res, next) {
            module.exports.isLoggedIn,
            function (req, res, next) {



               return next();
            }

I hope someone can give me a pointer on whats wrong/ or a solution
