for people who is looking for a workaround for this in the year 2015+ (since the post is of 2014).

I'm implementing a posts wizard pw_module where I need to update data reactively depending on the route parameters:

Router.route('/new-post/:pw_module', function(){
    var pwModule = this.params.pw_module;
    this.render('post_new', {
        data: function(){
            switch (true) {
                case (pwModule == 'basic-info'):
                    return {
                        title: 'Basic info'
                    };
                    break;
                case (pwModule == 'itinerary'):
                    return {
                        title: 'Itinerary'
                    };
                    break;
                default:
            }
        }
    });
}, {
    name: 'post.new'
});

Later in the template just do a:

{{title}}

Changing routes

The navigation that updates the URL looks like this:

    Basic info
    Itinerary

Hope it still helps someone.
