Class is not updating in Docs Guide

Hi!
In docs at http://ionicframework.com/docs/guide/building.html

This code is working only on start app or on adding new project:

<ion-list>
    <ion-item ng-repeat="project in projects" ng-click="selectProject(project, $index)" **ng-class="{active: activeProject == project}"**>
      {{project.title}}
    </ion-item>
  </ion-list>

Class is not updating on click.
p.s. sorry for my english.

Ok, I run it on browser and as i seen, “active” class is toggled on any “list” item on “click” event (maybe on “release”).
If i give class name “myactive”, its work!
Can you help me?

in nighltly release works good.
please close the theme.
