editor template return null value - asp.net

Question

I have created an editor template base on this article ASP.NET MVC: Annotated for Input by Dino Esposito
Everything works fine until i press the submit button. I find out that my POST function return model is NULL, its like the model is not bind to the view. I have been trying all trick that I know and I found from the internet but I still can't fix it.
This is my controller
// GET: /Asset/New
public ActionResult New()
{
ViewBag.typeID = new SelectList(db.Ref_Asset_Types, "ID", "name");
return View(new AssetViewModel());
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult New(AssetViewModel vm)
// vm.asset should contain new value but currently return null
{
if (ModelState.IsValid)
{
db.Assets.Add(vm.asset);
db.SaveChanges();
return RedirectToAction("Index");
}
ViewBag.typeID = new SelectList(db.Ref_Asset_Types, "ID", "name", vm.asset.typeID);
return View("New", vm);
}
this is my view
#using (Html.BeginForm("New","Asset","POST")) {
#Html.AntiForgeryToken()
#Html.ValidationSummary(true)
#Html.EditorFor(m=>m.asset, "InputTemplate" )
// note : the code works if i don't use my own template ==> #Html.EditorFor(m=>m.asset)
<div class="form-actions btn pull-right">
#Html.ActionLink("Back to List", "Index", null, new { #class = "btn btn-sm"})
<button type="reset" class="btn btn-sm" value="Index">
Reset
</button>
<button type="submit" class="btn btn-sm btn-success">
<i class="glyphicon glyphicon-plus"></i>
Tambah
</button>
</div>
}
and this is my InputTemplate
#inherits System.Web.Mvc.WebViewPage
#if (Model == null)
{
<span>#ViewData.ModelMetadata.NullDisplayText</span>
}
else
{
foreach (var prop in ViewData
.ModelMetadata
.Properties
.Where(pm => pm.ShowForDisplay && !ViewData.TemplateInfo.Visited(pm)))
{
if (prop.DisplayName != null) { // only display prop not of ComplexType
// note : using bootstrap for css styling
<div class="form-group col-xs-6">
<label class="col-xs-4 control-label text-right">
<span style="color:red"> #(prop.IsRequired ? "*" : "") </span>
<span>#prop.GetDisplayName()</span>
</label>
<div class="col-xs-8">
#if(prop.IsReadOnly)
{
<span class="readonly-field">#Html.Display(prop.PropertyName)</span>
}
else if (prop.TemplateHint == "DropDown")
{
<span>#Html.DropDownList(prop.PropertyName,(IEnumerable<SelectListItem>) ViewData[prop.PropertyName], new { #class = "form-control" })</span>
<span>#Html.ValidationMessage(prop.PropertyName)</span>
}
else
{
<div class="editor-field">
<span>#Html.Editor(prop.PropertyName, new { #class = "text-box single-line form-control" })</span>
<span>#Html.ValidationMessage(prop.PropertyName, new { #class = "label-danger" } )</span>
</div>
}
</div>
</div>
} // if
} // foreach
}
This is my viewmodel
using System;
using SIGMA.Models;
namespace SIGMA.ViewModels
{
public class AssetViewModel
{
public AssetViewModel()
{
asset = new Asset();
}
public Asset asset { get; set; }
}
}
This is my model
public class Asset
{
[Key]
[DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
[HiddenInput(DisplayValue = false)]
public int ID { get; set; }
[DisplayName("No. Siri")]
[StringLength(45)]
public string serial_num { get; set; }
[DisplayName("Model")]
[Required(ErrorMessage = "Model perlu diisi!")]
[StringLength(45)]
public string model { get; set; }
[DisplayName("Harga Seunit")]
[RegularExpression(#"^\d{0,6}(\.\d{2})?$", ErrorMessage = "Sila gunakan format harga yang betul.")]
public float? unit_cost { get; set; }
[UIHint("DropDown")]
[DisplayName("Jenis Aset")]
[Required(ErrorMessage = "Jenis aset perlu dipilih!")]
[DisplayFormat(NullDisplayText = "Belum didaftar")]
public int? typeID { get; set; }
public virtual Ref_Asset_Type type { get; set; }
}

Sorry guys for the trouble.. i think i solve it.
My biggest mistake is using reserved word 'model' and 'type' as my property name. This some how cause problem to asp.net in interpreting my model using the user define editor template.
Once I change my property name - model to model_name and type to asset_type, i can see the my entry in my return model already.
Thanks to all
.... spends the whole day and night for this silly mistake but the lesson learn is worth it
