ASP.NET MVC Ajax Post has no data - ajax

Question

I've struggled with this one for too long, maybe I'm missing something simple. I've been trying to use an ajax form to avoid reloading the whole page after submitting a form. Everything is looking fine, and Chrome DevTools is showing a good post holding all of my data. When I get to my action in the controller, my view model is empty and in its initialized state. So my though is it has something to do with the way the values are getting mapped to my model on the server side.
This is sort of my code, I was aiming for more than this but I've stripped a lot of it away while trying to trouble shoot. I feel like this is the most basic possible form of Ajax form post. I tried making the names and variables generic to try and simplify, so if something don't add up that might be why.
Please help I'm going crazy.
View:
#model EmiExpress.Web.Areas.Reports.Models.TurnkeyLiability.AddNewReportFormVm
#using (Ajax.BeginForm("NewReport", "Reports",
new AjaxOptions { HttpMethod = "POST" } ))
{
<div>
#Html.TextBoxFor(model => model.GroupId)
</div>
<div>
#Html.DevExpress().CheckBoxFor(
model => model.Save,
s =>
{
s.Text = "Save Values?";
}
).GetHtml()
</div>
<div>
<input type="submit" value="Submit Data" id="btnSubmit" />
</div>
}
Controller Action:
[HttpPost]
public ActionResult NewReport(AddNewReportFormVm viewModel)
{
int x = 5;
if (ModelState.IsValid)
{
x = 10; //just some junk while I try to get this working
}
return PartialView("Controls/_cbpReportRunLoading", x);
}
Model:
public class AddNewReportFormVm
{
public AddNewReportFormVm()
{
GroupId = "";
Save = false;
}
[Required]
public string GroupId{ get; private set; }
public bool Save{get; set;}
}
