Why is keyword not being rendered?

I've got the following. All works well. But {{keyword}} in app/templates/search/results.hbs is not being rendered at all...

Any pointers?

// app/router.js
import Ember from 'ember';
import config from './config/environment';

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

Router.map(function() {
  this.resource('search', { path: '/search' }, function() {
    this.route('results', { path: ':keyword' });
  });
};

// app/routes/application.js
import Ember from 'ember';

export default Ember.Route.extend({
  actions: {
    search: function(keyword) {
      this.transitionTo('search.results', keyword);
    }
  }
});

// app/routes/search/results.js
import Ember from 'ember';

export default Ember.Route.extend({
  model: function(params) {
    return Ember.RSVP.hash({
      products: this.store.find('product', { name: params.keyword, status: 'available' })
    });
  }
});

// app/templates/application.hbs
<form {{action "search" keyword on="submit"}}>
  {{input type="text" value=keyword placeholder="search" class="search"}}
</form>

// app/templates/search/results.hbs
<h3>Searching "{{keyword}}"</h3>
{{product-list products=products action='addToCart' fromRoute='index'}}
