Query Params broken with ObjectController on 1.11.0-beta.5

[craigteegarden]

Query params seem to not work correctly on Ember 1.11.0-beta.5 when using an ObjectController. The exact code functions when using Ember 1.10.0 or when using 1.11.0-beta.5 with the ObjectController replaced with a Controller.

When binding the query param property on the controller to an input in the template, editing the text field doesn't update the URL, but setting the URL manually does update the text field.

App.IndexController = Ember.ObjectController.extend({
  queryParams: ['category'],
  category: null
})

  <script type="text/x-handlebars" data-template-name="index">
    <span>Category: {{input value=category}}</span>
  </script>

Examples:

• broken: ObjectController on 1.11.0-beta.5 http://emberjs.jsbin.com/jihuyo/1/edit?html,js
• working: Controller on 1.11.0-beta.5 http://emberjs.jsbin.com/loxipo/2/edit
• working: ObjectController on 1.10.0 http://emberjs.jsbin.com/yeqoho/1/edit?html,js

I know ObjectController is deprecated, but if I understand the deprecation/Ember 2.0 strategy correctly, everything should still work correctly even if I still use ObjectController?
