title: Message does not appear when called from evaluate method
body: <p>I'm new to casperjs and playing around with it, but I can't get its <code>evaluate()</code> functionality to work.</p>
  
  <p>This is my example</p>
  
  <pre><code>var casper = require('casper').create();
  
  casper.echo('started...');
  
  casper.start('http://www.google.de/');
  
  casper.then(function() {
      this.echo(this.getTitle());
  });
  
  casper.then(function() {
      this.evaluate(function() {
          this.echo('test');
      });
  });
  
  casper.run();
  </code></pre>
  
  <p>I'm executing it with <code>casperjs sample.js</code></p>
  
  <p>After <code>started...</code> and <code>Google</code> nothing happens in console output. The closure function given in the evaluate method is not executed.</p>
  
  <p>I don't even get further informations by console with <code>--verbose</code>.</p>
  
  <p>What am I doing wrong?</p>
