Event binded in route Node.js

Question

I'm using expressjs along with nowjs, I'm binding some events to the now object right inside the route when it's being accessed. This isn't very clean, and I have the feeling everything the root is accessed the events are executed.

I'm not sure how, but I wonder if I could move this elsewhere?

app.get('/room/:name', function(req, res)
{
  //Should this code be moved elsewhere?... how?
  nowjs.on('connect', function()
  {
    this.now.room = req.params.name;
    nowjs.getGroup(this.now.room).addUser(this.user.clientId);
    console.log("Joined: " + this.now.name);
  });

  everyone.now.distributeMessage = function(message){
    nowjs.getGroup(this.now.room).now.receiveMessage(this.now.name, message);
  };

  res.render('room', { user : user });
});

You could separate the room code out into another module, perhaps even applying a pattern such as MVC to your app.

var Room = require('./models/room');

...

app.get('/room/:name', function(req, res) {
  Room.initialize(params.name);
  res.render('room', {user: user});
});

// models/room.js

Room = {
  initialize: function(name) {
    nowjs.on('connect', function() {
      this.now.room = name;
      nowjs.getGroup(this.now.room).addUser(this.user.clientId);
      console.log("Joined: " + this.now.name);
    });

    everyone.now.distributeMessage = function(message){
      nowjs.getGroup(this.now.room).now.receiveMessage(this.now.name, message);
    };
  }
};

module.exports = Room; // makes `require('this_file')` return Room

I'm not super familiar with Now.js, but you get the idea--but the code that doesn't concern the HTTP stack in another module, in another file, and require it and use it when necessary.
