title: ember.js contentIndex for each helper
body: <p>I have the following handlebars template:</p>
  
  <pre><code>   {{#each Lead.leads_controller}}
      &lt;tr&gt;
        &lt;td&gt;
          &lt;strong&gt;{{???}}&lt;/strong&gt;
        &lt;/td&gt;
        &lt;td class="plus expander"&gt;&amp;nbsp;&lt;/td&gt;
        &lt;td&gt;{{company}}&lt;/td&gt;
        &lt;td&gt;{{web}}/&lt;/td&gt;
        &lt;td&gt;{{phone_1}}&lt;/td&gt;
        &lt;td&gt;{{phone_2}}&lt;/td&gt;
        &lt;td&gt;{{fax}}&lt;/td&gt;
      &lt;/tr&gt;
      {{/each}}
  </code></pre>
  
  <p>I want to show a 1 based index for each row in a table.  I know previously the collectionView had contentIndex exposed but this does not appear to be the case for the each helper.</p>
  
  <p>I found <a href="https://github.com/emberjs/ember.js/issues/523" rel="nofollow">this</a> that seems to suggest that this is not available for the each helper.  Is there any way of making this possible for the each helper?</p>
