title: ng-model binding with item id
body: <p><strong>case:</strong></p>
  
  <p>I need to bind an input field with a specific hidden field, and I want to refer to it by ID because I have many of those input vs hidden input in my page.</p>
  
  <p>Something like this:</p>
  
  <p><strong>HTML:</strong></p>
  
  <pre><code>&lt;input type="text" ng-model="item.name-{{item.ID}}" &gt;
  
   &lt;input type="hidden" name="item_name" value="{{item.name-{{item.ID}}}}" &gt;
  </code></pre>
  
  <p>Item will be an object, where it looks like this:</p>
  
  <pre><code>$scope.item = {ID: '11111', name:'itemname'} 
  </code></pre>
  
  <p>The item name can be edited through this input field where we will insert the name and it will be binded to a hidden field to be submitted with the form.</p>
  
  <p>Thank you.</p>
