title: Not able to access controller variables on view using {{}} in angularjs
body: <p>I have an angular app deployed on Google App Engine (python).</p>
  
  <p>Whenever I try to access controller variables on View using {{}} notation, nothing happens.</p>
  
  <p>Controller </p>
  
  <pre><code>$scope.abc ="ABC"
  </code></pre>
  
  <p>On view</p>
  
  <pre><code>&lt;h2&gt;{{abc}}&lt;/h2&gt;
  </code></pre>
  
  <p>This works if I run my app on local without app engine. but after deployment same code does not work.</p>
  
  <p>I have googled this but didn't get anything. What is the issue with {{}} ?</p>
