How to send html code to ckeditor using ajax?

Question

CKEditor

ajax script

function call() {
 	  var msg   = $('#title').serialize();
        $.ajax({
          type: 'POST',
          url: 'stranajax/ajax.php',
          data: msg,
         success: function(data) {
            $('#htmlx').html(data);
          },
          error:  function(xhr, str){
      alert('Возникла ошибка: ' + xhr.responseCode);
          }
        });
    }

"htmlx"- id in ckeditor in this case nothing changes
tried to cling id to the block in which ckeditor was placed and already write ck in ajaxe, but then only textarea appeared.
