You will have to turn your object into array in order to get it to work

<div ng-controller="MyCtrl">
  <div ng-repeat="line in lines | orderBy:'name'">
    <div class="preview">{{line.name}} {{$index}}</div>
  </div>
</div>

and controller

var myApp = angular.module('myApp', []);

function MyCtrl($scope) {
    $scope.lines = [
       {name:"bb"},
    {name: 'aa'},
    {name:"zz"},
    {name: 'oo'}, 
    {name:"k"},
    {name: "a"},
    {name:"n"},
    {name: "c"}
];
}
