title: twig variable in ng-show
body: <p>There is a way to write:</p>
  
  <pre><code>&lt;th ng-show=" {{ 'item._type' }}  != null"&gt; Type&lt;/th&gt;
  </code></pre>
  
  <p>and the twig part:</p>
  
  <pre><code>{% include "@fileName" with item: 'entity' %}
  </code></pre>
  
  <p>Right now it gives me the error: </p>
  
  <pre><code> Unexpected token "punctuation" of value ":" ("end of statement block" expected).
  </code></pre>
