title: update variable in module pattern
body: <p>I'm trying to set the value of a private variable through a module pattern.
  So what I'm saying is set $content to the value I'm passing to person.content. But this doesn't seem to work because when I do an alert  on the value it gives me an undefined error.</p>
  
  <pre><code>$(document).ready(function(){
      person.content = $('#content');
      person.getContent();
  
  });
  
  // Person Module
  var person = ( function(){
  
          var $content;
  
  
          function getContent(){
                  alert( 'content = '+$content.find(':first h2').text());
          }
  
          return { 
              content: $content,
              getContent : getContent,
  
          }
  
      }( ) );
  </code></pre>
