title: Angular 2: String interpolation with function call
body: <p>I am developing my first Angular app and having trouble with string interpolation.</p>
  
  <p>I have a component which contains the following element:</p>
  
  <pre><code>`&lt;span&gt;{{action.getText()}}&lt;/span&gt;`
  </code></pre>
  
  <p>action is of Type Action which has the following method:</p>
  
  <pre><code>getText(): String { return "Test"; }
  </code></pre>
  
  <p>The variable action is defined correctly since I can access properties via {{}} without a problem. e.g. <code>{{action.title}}</code></p>
  
  <p>So my question is, is this even possible to access this function and if yes, what am I doing wrong?</p>
