title: enqueue_script not working
body: <p>quick question here. </p>
  
  <p>I am adding custom javascript to my wordpress site, i have header-tab.js saved in the child theme's js folder, and tried to call on it with enqueue_script in my child theme's functions.php as shown here: </p>
  
  <pre><code>function includes_header_tab()
  {
  wp_enqueue_script( 'header-tab', get_template_directory_uri() .'/js/header-tab.js', array( 'jquery' )); 
  }
  add_action('wp_enqueue_scripts', 'includes_header_tab');
  ?&gt;
  </code></pre>
  
  <p>this does not seem to work, can anyone see if there is a problem in my code? or am i missing something? or it might be my javascript file that is at fault? </p>
