Hi Guys!

I'm trying to put together a form using Surface controller, but when submitting the form, the browser redirects to /umbraco/Surface/InsightsSignup/SubmitForm

The values from the form arrives to the controller, strangely.

I'm using Umbraco v8.4.0

View:

@inherits UmbracoViewPage<InsightsSignupModel>

@using package.Models
@using package.Controllers


        @if (TempData["value"] != null)
        {
            <p>Done</p>
        }
        else
        {
            using (Html.BeginForm("SubmitForm", "InsightsSignup", FormMethod.Post))
            {
                @Html.TextBoxFor(m => m.Name, new { @class = "form-control", placeholder = "Name..." })
                @Html.TextBoxFor(m => m.Company, new { @class = "form-control", placeholder = "Company..." })
                @Html.TextBoxFor(m => m.Email, new { @class = "form-control", placeholder = "Email..." })

                <button type="submit">Submit</button>
            }
        }

SurfaceController:

namespace package.Controllers
{
    public class InsightsSignupController : Umbraco.Web.Mvc.SurfaceController
    {
        [HttpGet]
        public ActionResult RenderForm()
        {
            InsightsSignupModel model = new InsightsSignupModel() { FormPageId = CurrentPage.Id };
            return PartialView("InsightsSignupSurface", model);
        }

        [HttpPost]
        public ActionResult RenderForm(InsightsSignupModel model)
        {

            return PartialView("InsightsSignupSurface", model);
        }

        [HttpPost]
        public ActionResult SubmitForm(InsightsSignupModel model)
        {
            bool success = false;

            if (ModelState.IsValid)
            {
                success = true;
            }

            if (success)
            {
                TempData["value"] = "returned";
            }

            return PartialView("~/Views/Partials/InsightsSignupSurface.cshtml");

        }
    }
}

Thanks, Istvan
