how to display an exception message

Hi all
I am doing batch editing in telerik mvc3.By clicking savechanges button in the grid it updates the database for this am using ajax options.if any error occurred while saving records an exception message is throwing but I want to display that exception message in my view page i tried this coding but not working properly

 function OnSuccess( e ) {
       var container =  $(".msg_container");    
        if(e.HasError==false)
            { 
                 var grid = $("#grdHolidays").data("tGrid");
                 grid.rebind(); 
                 alert("Saved");
            }
         else
            {    
                 showMessage(e.Message.MessageCode, e.Message.Message,                   e.Message.MessageType ,container);
                  alert("Error occurred");   
            }
    }  

I had called this function on OnSuccess event.Alert message "Error occurred" is coming but show message is not working. that MessageCode,message and messsagetype are having values also
