title: autoComplete CakePHP 2.0
body: <p>Since CakePHP 1.3, the Ajax helper has been deprecated, one cannot user $ajax->Autocomplete..</p>
  
  <p>I use Cake 2.0, and wish to implement dynamic autocomplete( dynamic table, dynamic field) it seems impossible with current tutorials available.</p>
  
  <p>What is closest alternative to $ajax->autoComplete in cakephp 2.0?</p>
