title: Calling jQuery Function on Selector
body: <p>I'm having an issue where I'm trying to call a function on a selector, and use jQuery to edit/add classes to elements within that selector.</p>
  
  <p>Below is my code:</p>
  
  <pre><code>(function($) {
      $(document).on('click', '.one a.button', function(){
          $('.two').loadQuestions();
      });
  })(jQuery);
  function loadQuestions( $ ) {
      $(this).addClass('active');
      $(this).children().addClass('transition-in');
      $(this).find('.tilt').delay(100).textillate({ 
          in: { effect: 'fadeInLeft' } 
  });
  </code></pre>
  
  <p>It keeps giving me this error:</p>
  
  <pre><code>undefined is not a function - in regards to:
      $('.two').loadQuestions();
  </code></pre>
