How can I get result from action? I need to show the commentID on the page (aspx) after successes comment insert.

controller

[AcceptVerbs(HttpVerbs.Post )]
        public ActionResult ShowArticleByAjax(Guid id, string commentBody)
        {

            Guid commentID = Comment.InsertComment(id, commentBody);

            //How can I tranfer  commentID to the  aspx page ???                 
            return PartialView("CommentDetails",Article.GetArticleByID(id));
          }

<%using (Ajax.BeginForm("ShowArticleByAjax", new {  id = Model.ID },
               new AjaxOptions { 
                                                HttpMethod = "Post",
                                                UpdateTargetId = "divCommentDetails",
                                                OnSuccess = "successAddComment",
                                                OnFailure = "failureAddComment",
                                                OnBegin = "beginAddComment"
