title: Using add_action hook of GravityForms add-on stickylist
body: <p>GravityForms has a simple action hook that can be used after submission</p>
  
  <blockquote>
    <p>add_action( 'gform_after_submission', 'my_function', 10, 2 );</p>
  </blockquote>
  
  <p>my_function is any user-defined function where the call reaches if the action hook is found in functions.php</p>
  
  <p>StickyList, an add-on built on GravityForms also provides an action hook that can be used after the form is submitted. It is here below</p>
  
  <blockquote>
    <p>add_action("gform_after_submission", array($this, "post_edit_entry"),
    10, 2);</p>
  </blockquote>
  
  <p>My question is, how does one use the <em>my_function</em> to the StickyList action hook which hasn't specified/documented how to use this action hook. I don't know what the array is doing as a second argument and how to get the call to reach my user defined function once this action_hook is found in functions.php.</p>
