title: Ajax Autocomplete for Jquery : not able to use methods such as setOptions or disable
body: <p>I am using Ajax Autocomplete for Jquery (<a href="http://www.devbridge.com/projects/autocomplete/jquery/" rel="nofollow">http://www.devbridge.com/projects/autocomplete/jquery/</a>). With version 1.1, you can declare an autocomplete instance as a variable and then use methods such as setOptions, enable, or disable to dynamically alter the autocomplete:</p>
  
  <pre><code>var ac = $('#query').autocomplete(options);
  ac.disable();
  ac.enable();
  ac.setOptions({ zIndex: 1001 });
  </code></pre>
  
  <p>This is not working for me in the latest version (1.2.4), and I get the following example error message: <code>Uncaught TypeError: Object [object Object] has no method 'disable'</code>. </p>
  
  <p>I could use the older version, but there is some new functionality in v1.2 I would like to use. Any ideas how to dynamically change the autocomplete options in v1.2? Thanks. </p>
