ember.js - Assigning 'active' class to selected list item in EmberJS

Question

I have a list and I'd like to set one item as class="active" automatically. Given the following bootstrap code:

<ul class="nav">
<li {{bindAttr class="atIndex:active"}}>{{#linkTo "index"}}Index{{/linkTo}}</li>
<li {{bindAttr class="atAbout:active"}}>{{#linkTo "about"}}About{{/linkTo}}</li>
<li {{bindAttr class="atLogin:active"}}>{{#linkTo "login"}}Login{{/linkTo}}</li>
</ul>

atIndex, atAbout and atLogin reside in my ApplicationController.

To render as:

<ul class="nav">
<li class="active"><a...>Index{{/linkTo}}</li>
<li><a...>About<a></li>
<li><a...>Login<a></li>
</ul>

What's the best way to do this with Ember 1.0 pre4? I'd rather not add special code to every view or controller.

PS - atIndex: true works, but atIndex: function() {return true; }.property().volatile() does not. Which makes me think I'm doing something wrong.

Thank you!
