title: Call function from string inside object?
body: <p>I have a function name in a string: </p>
  
  <pre><code> var func = "doTest";
  </code></pre>
  
  <p>I need this function to be applied to the current instance ("this");</p>
  
  <p>So I need it to call:</p>
  
  <pre><code> this.doTest();
  </code></pre>
  
  <p>How can I do this? I cannot go via window.</p>
  
  <p>Thanks,
  Wesley</p>
