title: angularjs filter (not working)
body: <p>The following HTML, Javascript and JSON render correctly, but the filter does not work at all. What are we doing wrong?</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;div data-ng-controller="dashboard_controller"&gt;
      &lt;h1&gt;
          Catalogs
          &lt;input type="text" data-ng-model="catalog_filter" placeholder="Filter Distributors"&gt;
      &lt;/h1&gt;
  
      &lt;div class="catalogs_listing"&gt;
          &lt;ul data-ng-repeat="catalog in catalogs | filter:catalog_filter"&gt;
              &lt;li&gt;&lt;a href="{{catalog.distributor_id}}/d/products/catalog_view/{{catalog.uid}}"&gt;
                  &lt;div class="catalog_thumb"&gt;
                      &lt;div class="catalog_thumb_image"&gt;
                          &lt;img src="{{catalog.thumb_image}}" /&gt;
                      &lt;/div&gt;
                  &lt;/div&gt;
                  &lt;div class="catalog_info"&gt;
                      &lt;h2&gt;{{distributors[catalog.distributor_id].name}}
                          &lt;span&gt;{{catalog.products_count}}p&lt;/span&gt;
                      &lt;/h2&gt;
                      &lt;p&gt;{{catalog.name}}&lt;/p&gt;
                  &lt;/div&gt;
                  &lt;/a&gt;
              &lt;/li&gt;
          &lt;/ul&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>The Javascript:</p>
  
  <pre class="lang-js prettyprint-override"><code>app.controller('dashboard_controller', function ($scope, $http) {
      $http.get('./api/distributors/my').then(function (res) {
          $scope.distributors = res.data;
      });
      $http.get('./api/dashboard/catalogs').then(function (res) {
          $scope.catalogs = res.data;
      });
  });
  </code></pre>
  
  <p>And these 2 JSONs:</p>
  
  <p><strong>api/distributors/my:</strong></p>
