title: Masked input: I can't get the simplest completion to work
body: <p>Trying to use Josh Bush's masked input plugin.</p>
  
  <p>I want to shift focus and do other things once the person puts their cell phone in. I mask to a phone shape. When I hit the last letter, I want it to trigger a JavaScript function. Right now that function just alerts "hi".</p>
  
  <p>I even copied the demo right off Josh Bush's page: <a href="http://digitalbush.com/projects/masked-input-plugin/" rel="nofollow noreferrer">http://digitalbush.com/projects/masked-input-plugin/</a> the third one for triggering something to complete. Copying it verbatim and it still doesn't work?</p>
  
  <p>Am I crazy? Can anyone get this to work.</p>
  
  <pre><code>function jump(){
      alert('hi');
  }
  
  $(document).ready(function(){
      $("#cellphone").focus();
      jQuery(function($){
          $("#product").mask("(999) 999-9999",{completed:function(){jump();}});      
      });
   });     
  </code></pre>
