title: How to call a function of a parent class from another function in jquery
body: <p>I guess that's the simple question. I'm new in <code>js</code>, especially in <code>Backbone.js</code>.</p>
  
  <p>All I want to know is how I can refer to my function inside jquery function.</p>
  
  <pre><code>getLanguages: function() {
  
     ...
  
     return languages;
  },
  
  render: function() {
  
      ...
  
      $("input[type='checkbox']").bind("change", function() {
  
         // todo: getLanguages
      });
  
  }
  </code></pre>
  
  <p>I tried to get languages via <code>this</code> but, of course, I got <code>checkbox</code> in this case.</p>
  
  <p><strong>Edit:
  It's so simple. Many thanks to all!!!</strong></p>
