Case Closed - Pass JSON data to Controller MVC - asp.net-mvc

Question

I want to pass this data from my view to save it via controller.
My view
<div>
<b>Title</b> <br />
<input type="text" id="title" /><br />
<b>Description</b> <br />
<input type="text" id="desc" /><br />
</div>
<button id="saveDetails">Save</button>
My js
$(document).ready(function () {
$(document).on("click", "#saveDetails", saveDetails);
$("#detailsPanel").hide();
});
var saveDetails = function () {
var dataPost = {
"Title": $("#title").val(),
"Description": $("#desc").val(),
"AssetId": $("#assetId").val()
}
$.ajax({
type: "POST",
async: false,
contentType: "application/json",
data: JSON.stringify(dataPost),
url: "/Media/Save"
}).done(function (state) {
if (state.Saved == true) {
displayStatusMessage("Saved Successfully");
$("#detailsPanel").hide();
mediaPlayer.initFunction("videoDisplayPane", state.StreamingUrl);
} else {
displayStatusMessage("Save Failed");
}
});
}
My Controller
[HttpPost]
public JsonResult Save(MediaElement mediaelement)
{
try
{
mediaelement.UserId = User.Identity.Name;
mediaelement.FileUrl = GetStreamingUrl(mediaelement.AssetId);
db.MediaElements.Add(mediaelement);
db.SaveChanges();
return Json(new { Saved = true, StreamingUrl = mediaelement.FileUrl });
}
catch (Exception ex)
{
return Json(new { Saved = false });
}
}
Its already post the data to my controller (i saw it via Fiddler), but it always return Json(new { Saved = false }).
Anything wrong with my code? Need help, please...
[Case Closed]
Okay, I found in my db, i have coloumn UploadDate which is not null. And I already declare the default value on my db with this -> getdate(). But it doesnt work when I inserted data from controller. So i add the value of UploadDate manually via Controller. Then Its Works:)
Thanks everybody :)

i think the problem is with the MediaElement model binding ...
but before, check the folowing :
you can try to remove the JSON type of your ajax.
your json format.
the dataPost var miss the ; end.
$(document).ready(function () {
$(document).on("click", "#saveDetails", saveDetails);
$("#detailsPanel").hide();
});
var saveDetails = function () {
var dataPost = {
Title: $("#title").val(),
Description: $("#desc").val(),
AssetId: $("#assetId").val()
};
$.ajax({
type: "POST",
async: false,
data: dataPost,
url: "/Media/Save"
}).done(function (state) {
if (state.Saved == true) {
displayStatusMessage("Saved Successfully");
$("#detailsPanel").hide();
mediaPlayer.initFunction("videoDisplayPane", state.StreamingUrl);
}
else {
displayStatusMessage("Saved Failed");
}
});
}
