jQuery Form plugin doesn't calls Method in IE 8 - ajax

Question

I am trying to upload files to server, but when i am submitting form it doesn't calls ActionResult. It works in chrome, FF but not in IE. When i am removing enctype="multipart/form-data" attribute from form in IE, then it calls method, but without file uploading...
I have such input:
<input id="jqueryfileupload" type="file" name="files" data-upload-id="#documentUniqueId"
data-url="#Url.Action(MVC.Profile.Documents().AddRouteValue("documentUniqueId", documentUniqueId))" multiple>
jQuery code:
$(document).on('change', '.documents-upload-container #jqueryfileupload', function (e) {
e.preventDefault();
e.stopPropagation();
var $this = $(this);
//input itself is not in the form tag, so i am creating form here and
//submitting it this way
var formContainer = $('<form action="' + $this.data('url') + '" enctype="multipart/form-data" method="POST"></form>');
$this.appendTo(formContainer);
var contentTypeOption = $.browser.msie ? 'text/html' : 'application/json';
var iframeOption = $.browser.msie ? true : false;
var options = {
dataType: 'json',
//contentType: contentTypeOption,
//iframe: iframeOption,
method: 'POST',
success: function (response, textStatus, xhr, form) {
alert(response);
},
error: function (xhr, textStatus, errorThrown) {
alert(xhr);
alert(textStatus);
alert(errorThrown);
},
clearForm: true
};
$(formContainer).ajaxSubmit(options);
return false;
});
There are no errors and alerts are not throwing at all in IE. Just method is not called...
Action Method:
[HttpPost]
public virtual ActionResult Documents(IEnumerable<HttpPostedFileBase> files, string documentUniqueId)
{
var result = new ContentResult();
if (files != null)
{
foreach (var item in files)
{
string docName = documentUniqueId + "_" + item.FileName;
var filename = Path.Combine(Server.MapPath("~/App_Data"), docName);
item.SaveAs(filename);
}
var docs = files.Select(x => new
{
url = Url.Action(MVC.Profile.Documents(documentUniqueId + "_" + x.FileName, x.ContentType)),
name = x.FileName,
contentType = x.ContentType,
id = documentUniqueId + "_" + x.FileName
});
result.Content = new JavaScriptSerializer().Serialize(docs);
return result;
}
result.Content = new JavaScriptSerializer().Serialize(new { success = false });
return result;
}
[HttpGet]
public virtual ActionResult Documents(string fileName, string contentType)
{
var docPath = Path.Combine(Server.MapPath("~/App_Data"), fileName);
return File(docPath, contentType);
}
I use this plugin : http://malsup.com/jquery/form/

I think you are not inserting the form in the page. that's the problem. you have to add formContainer.appendTo(container);
try this code:
$(document).on('change', '.documents-upload-container #jqueryfileupload', function (e) {
e.preventDefault();
e.stopPropagation();
var $this = $(this);
var container = $this.parents('.documents-upload-container').addClass("current-container");
var formContainer = $('<form action="' + $this.data('url') + '" enctype="multipart/form-data" method="post"></form>');
$this.appendTo(formContainer);
formContainer.appendTo(container);
var contentTypeOption = $.browser.msie ? 'text/plain' : 'application/json';
var iframeOption = $.browser.msie ? true : false;
var options = {
dataType: 'json',
contentType: contentTypeOption,
//iframe: iframeOption,
method: 'POST',
//data: { 'isIE': iframeOption },
success: function (response, textStatus, xhr, form) {
alert(response);
},
error: function (xhr, textStatus, errorThrown) {
alert(xhr);
alert(textStatus);
alert(errorThrown);
},
clearForm: true
};
formContainer.ajaxSubmit(options);
return false;
});
