debugging javascript in a view

You need to have two functions inside your controller. I have a separate index and json function.
You put everything inside org_chart_management and that's not going to work. Now it's echoing your html out as json.

You also have your url wrong in the ajax.

Code:

var jsonData = $.ajax({
  url: "/index.php/configure/json", // Here is the second function that you forgot to create
  dataType: "json",
  async: false
}).responseText;
