title: f:ajax by onchange event
body: <p>I have a special problem: I need to send a value to server by client onchange event without submiting the whole form. Is there some feature to do it?</p>
  
  <p>I can handle the component by Javascript:</p>
  
  <pre><code>&lt;h:inputText onchange= ...js... &gt;
  </code></pre>
  
  <p>And I can send a value by ajax:</p>
  
  <pre><code>&lt;f:ajax execute="name"/&gt;
  </code></pre>
  
  <p>How to put it together?</p>
  
  <hr>
  
  <p>It is solved, but I have another question:</p>
  
  <p>What is processed sooner - Ajax handling of the event or JavaScript handling?</p>
