  &lt;body&gt;
      &lt;script type="text/javascript"&gt;
          $(document).ready(function(){
              function call_back(data){
                  console.log("In callback function");
                  console.log(data);
              }
  
  
              $.ajax({

                  type: "POST",
                  dataType: 'jsonp',
