<h1>Welcome to $scope example</h1>
<div>
There is a solid blue line around each .ng-scope element.
</div>
<div ng-repeat="roles in user.roles">
{{user.name}}
{{roles.name}}
</div>
<div>
Type here to change user.name value: <input type="text" ng-model="user.name" />
<br/>
Type here to change just the first role's name value: <input type="text" ng-model="user.roles[0].name" />
</div>
<br/>
<div>
Hope this helps...
