routing to page doesn't update collection in backbone

I have this set up in my router for #hello

hello: function() {
    var greetingCollection = new Greetingcollection();
    greetingCollection.userId = app.user.get("id");
    greetingCollection.fetch({
    success: function(grModel){
      app.show(MyGreetingView, { model: grModel});
    },
    error: function(){
      alert('error caused at hello route!!');
    }
    })
},

When i am in another route and add to the model using

this.model.save(

I redirect back to the #hello route, but the new record is not in there?

If i do a hard refresh of the whole page, the new records now appear.

My question is how can i get the collection to be up to date after the model.save or reroute to a page that shows the collection.
