title: How to use multiple controller in one directive angularjs?
body: <p>Is it correct to use multiple controllers like below?</p>
  
  <pre><code>&lt;div ng-if="actionButtonText=='Confirm'" ng-controller="upsrCtrl" ng-controller="pt3Ctrl" ng-controller="spmCtrl"&gt;
      &lt;button ng-click="checkAnswer()" class="button button-confirm-outline"&gt;
          {{actionButtonText}}
      &lt;/button&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>The reason I used these were I make this as footer and the content change dynamically based on different controller.</p>
