AngularJS ng-click not invoked with {{$index}} used

For some reason AngularJS does not fire off the event when {{$index}} is used in ng-click.

My html:

<div ng-controller="Ctrl">
  <ul>
    <li ng-repeat="foo in foos">
     <label>{{foo.name}}</label>
     <a href="#" ng-click="remove({{$index}})">X (doesnt work)</a>
     <a href="#" ng-click="remove(0)">Remove first element (works)</a>
    </li>
  </ul>
 </div>

Anyone knows how to fix this? Thanks
