title: AngularJS bind value into data attribute
body: <p>Does anyone know how to bind an interpolated value into a data attribute using AngularJS?</p>
  
  <pre><code>&lt;input type="text" data-custom-id="{{ record.id }}" /&gt;
  </code></pre>
  
  <p>Angular doesn't seem to interpolate that value since its apart of the structure of the element. Any ideas how to fix this?</p>
