title: AJAX update div without creating partial
body: <p>I have some page:</p>
  
  <pre><code>title = "page"
  url = "/page"
  layout = "default"
  ==
  function onTest()
  {
      $this['result'] = 'Test string';
  }
  ==
  
  &lt;!-- AJAX enabled form --&gt;
  &lt;form data-request="onTest" data-request-update="mypartial: '#myDiv'"&gt;&lt;/form&gt;
  
  &lt;!-- Result container --&gt;
  &lt;div id="myDiv"&gt;&lt;/div&gt;
  </code></pre>
  
  <p>After submitting the form I can get 'result' variable only in partial 'mypartial', where code is: <code>Here  is {{ result }}</code>. And this code inserts into #myDiv.</p>
  
  <p>How can I get 'result' variable without creating partial? Why should I create .htm file (partial) for each little AJAX query?</p>
