How to get profile data from facebook using passport.js authentication?

In the below code the 'console.log('this does not print!')' statement does not execute. It should execute according to the FacebookStrategy.

passport.use( new FacebookStrategy({clientID: FACEBOOK_APP_ID, clientSecret: FACEBOOK_APP_SECRET, callbackURL: "/home"}, function(identifier, profile, done) {

process.nextTick(function () {
  console.log(' This does not print!');
  return done(null, profile);
  }
);}));

Basically, the authentication thru passport-facebook takes place but I am not able to recover any profile data.

app.get('/home', function(req, res){
    console.log(req.user);
    res.render('home', {user: req.user});
});

The above prints 'undefined' which means that the above app.get(...) did not receive the facebook profile data.

What am I doing wrong? Is there anyway to save (get) facebook profile data after authentication?
