title: Nested ng-repeat is never called
body: <p>I'm new in angular and I'm trying to access some datas inside a variable in which there is tab nested in another tab. (I can't link it because it's sensitive). Anyway, I'm trying to use a nested ng-repeat to access it, but the second ng-repeat is never called, and my console doesn't give me a single error message. This is basically how it looks.</p>
  
  <pre><code>dico = [
      { ...
      content : []
      },
      { ...
      content : []
      },
      ...
  ];
  </code></pre>
  
  <p>After checking existing questions (<a href="https://stackoverflow.com/questions/19206760/angular-nested-ng-repeat-failure#_=_">https://stackoverflow.com/questions/19206760/angular-nested-ng-repeat-failure#<em>=</em></a> &amp; <a href="https://stackoverflow.com/questions/15256600/passing-2-index-values-within-nested-ng-repeat">passing 2 $index values within nested ng-repeat</a>) I don't get why my part isn't working.</p>
  
  <pre><code>  &lt;span ng-repeat="toolbar in dico"&gt;
          &lt;candidate-toolbar-review average="toolbar.average" labeltoolbar="{{toolbar.name}}"&gt;
               &lt;span ng-repeat="field in toolbar.content" layout="row" layout-wrap layout-align="start center"&gt;
                  &lt;candidate-field-review labelfield="{{field.name}}" ng-model="field.value" my-model="field.checked"&gt;
                  &lt;/candidate-field-review&gt;
               &lt;/span&gt;
          &lt;/candidate-toolbar-review&gt;
      &lt;/span&gt; 
  </code></pre>
  
  <p>In this sample of code, both candidate-field-review and candidate-toolbar-review are directives, if I comment the first one, the second one will output correctly. Elsewise, the first one is printed as expected.</p>
  
  <p>I tried to use $parent and track by $index, but I don't really understand how those work. I also tried to use div instead of span or to not use span at all (and include the ng-repeats inside the candidate-toolbar and candidate-field). What am I missing here ? Thanks !</p>
  
  <p><strong>EDIT :</strong>
  I used those lines instead and it worked out. I still don't really know why it wouldn't work the other way around though.</p>
  
  <pre><code>            &lt;span ng-repeat="toolbar in dico"&gt;
                  &lt;candidate-toolbar-review ng-model="toolbar.average" labeltoolbar="{{toolbar.name}}" ng-click="showSmart=!showSmart"&gt;
                  &lt;/candidate-toolbar-review&gt;
                  &lt;span ng-repeat="field in toolbar.content"&gt;
                      &lt;candidate-field-review labelfield="{{field.name}}" ng-model="field.value" my-model="field.checked"&gt;
                      &lt;/candidate-field-review&gt;
                  &lt;/span&gt;
              &lt;/span&gt;
