Question

I got the following insistent JS issue just for IE 8-9, in other browsers my code working very well.

Case:
I have the following code in JS, which should start some server process and update progress bar with status on server side, what Jquery UI provide:

 $("#btnSendUser").click(function (event) {                
                $.ajax({
                    type: "POST",
                    url: "/StartLongProcess",
                    dataType: "json",
                    traditional: true,
                    data: { userIds: users },
                    success: function (result) {
                        console.log("Process start");
                    }
                });
                var processId = 0;
                getStatus(processId);
            });

        function getStatus(processId) {
            var url = '/GetStatus';
            $.get(url, { clientProcessId: processId }, function (data) {
                if (!data.IsDone) {
                    $("#progress").progressbar({ value: data.Progress });                                        
                    window.setTimeout("getStatus(" + processId + ")", 350);
                }
                else {
                    $("#progress").progressbar({ value: 100 });      
                    console.log("Done");                                                            
                };
            });                                  
        }

In StartLongProcess method in current controller I starting long server process in this way:
..

[ValidateInput(false)]
        public void StartLongProcess(Guid[] userIds)
        {       
            ...
            var processTask = new LongProcess(MesssageService.Email.SendMails);
            processTask.BeginInvoke(service.LongProcess(userIds), new AsyncCallback(EndSendingProcess), processTask);
        }

Method that read current status is next:

 /// <summary>
        /// Gets the current progress.
        /// </summary>
        /// <param name="id">The id.</param>
        public JsonResult GetCurrentProgress(int clientProcessId)
        {
            ControllerContext.HttpContext.Response.AddHeader("cache-control", "no-cache");
            var currentProgress = MesssageService.Email.GetCurrentLog(clientProcessId);            
            return Json(currentProgress ?? new LogMessage(0), JsonRequestBehavior.AllowGet);
        }

I tested this code in Chrome and FF, in those browsers progress bar and process finished correctly always. But in IE 8-9 it looks like getStatus function can’t be called in this way. Is it true? What is the best way to implement my task for all browsers?
Thanks.

@cleric Can always try

window.setTimeout(function() {getStatus(processId)},350);

rather than

window.setTimeout("getStatus(" + processId + ")", 350);
