title: How can I enable and pass a data-test attribute to a component in Ember 2.16?
body: <p>I have a basic component called like this:</p>
  <pre><code>{{my-component
      // more data here
      data-test-my-component=&quot;filter-questions&quot; 
  }}
  </code></pre>
  <p>and I am binding the attributes like this:</p>
  <pre><code>attributeBindings: [
      // more data here
      'data-test-my-component',
    ],
  </code></pre>
  <p>But I do not see this data attribute populated in my HTML.</p>
