Ember passing a model to transitionToRoute

I'm using Ember-cli with ember 1.11

I'm trying to use the transitionToRoute method in a controller to transition to a route and feed it a dynamically generated object as the model.

Here's my controller:

import Ember from 'ember';

export default Ember.Controller.extend({
  actions: {      
      launch_scanner: function(){
        console.log('launch_scanner');
        var model = {name: "Edward", phone: "123", email: "email@test.com"};
        //the final app will pull the model variable from a QR scanner

        this.transitionToRoute('addcontact', model);
     }
  }      
});

When I trigger this action, the transitionToRoute method causes this error:

Uncaught Error: More context objects were passed than there are dynamic segments for the route: addcontact

If I leave out the model parameter, it transitions to the addcontact route just fine. What am I doing wrong?

Here is my router file:

import Ember from 'ember';
import config from './config/environment';

var Router = Ember.Router.extend({
  location: config.locationType
});

Router.map(function() {
  this.route('home', {path: '/'});
  this.resource('addcontact', {path: '/addcontact'});
});

export default Router;
