Ember js - model not refreshed with new query params

// controllers/list.js
import Ember from 'ember';

export default Ember.Controller.extend({
  queryParams: ['page', 'sortBy', {
    refreshModel: true
  }],
  page: 1,
  sortBy: 'createdAt'
});

and

// templates/components/list-table.hbs
Sort by name

Why list model is not fully refreshed, when I click "Sort by name" link? What I'm doing wrong? Thanks for any help.
