title: AngularJS : Variables in ng-model
body: <p>I have a loop ng-repeat</p>
  
  <pre><code>&lt;div ng-repeat="data in datas"&gt;
  Name: {{data.name}} &lt;input type="text" ng-model="age"&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I want <code>$scope.age</code> become to <code>$scope.age_data.name</code>. Eg: <em>$scope.age_Tan</em>, <em>$scope.age_Jim</em>...
