Data in redirected page is updated only after refresh (node.js)

I have a node.js website that i build with this tutorial: https://scotch.io/tutorials/easy-node-authentication-setup-and-local

I update some data in routes.js and than redirect to one of my views (.ejs):

    app.post('/setScore', isLoggedIn, function (req, res) {
    Real.find({'_id': req.body.realID}).exec(function (err, real) {
        real.forEach(function (real1) {
            real1.local.scoreH = req.body.home;
            real1.local.scoreA = req.body.away;
            real1.save(function (err) {
                if (err)
                    throw err;
            })
        })
    }); ......
//.... 


                                        res.render('league.ejs', {

                                        });

the page don't show the data that i had updated. only after i refresh the page the updated data is shown.

how can i solve it so the data will shown on page right after redirecting?
