CustomValidation not working on asp.net mvc form?

Hi Team

I need some help, my customValidation does not work and when i debug its showing any error. Please assist mates, basically the logic i want when leaving the [email protected](). Must validate message error "This field is required".

// Model class
[Required(ErrorMessage = "This field is required")]
[DataType(DataType.PhoneNumber)]
public string CellNumber { get; set; }
// CustomValidation.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using eNtsaRegistrationTraining.Models;
using System.ComponentModel.DataAnnotations;
namespace eNtsaRegistrationTraining.CustomValidation
{
public class CustomFormValidation:ValidationAttribute
{
protected override ValidationResult IsValid(object value, ValidationContext validationContext)
{
var registration = (TrainingRegForm)validationContext.ObjectInstance;
if(registration.CellNumber==null)
{
return new ValidationResult("This field is required");
}
return base.IsValid(value, validationContext);
}
}
}
// Controller.
//GET:TrainingRegForm/Create/WebRequest.
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult SubmitRegDetails([Bind(Include= "Id, Title, FirstName, LastName, Position, Company, StreetAddress, StreetAddressLine, City, StateProvince, ZipCode,Email, CellNumber, DietaryRequirement")]TrainingRegForm eNtsaTraining)
{
if(ModelState.IsValid)
{
eNtsaTraining.Id = Guid.NewGuid();
db.TrainingRegs.Add(eNtsaTraining);
db.SaveChanges();
return RedirectToAction("SaveRegForm");
}
// Validates when empty.
if(ModelState.IsValid)
{
return RedirectToAction("SaveRegForm");
}
return View(eNtsaTraining);
}
// View
div class="form-group row">
for="Attendee" class="col-sm-2 col-form-label">Attendee Cell Number*
class="col-sm-3">
@Html.EditorFor(model => model.RegForm.CellNumber, new { htmlAttributes = new { @class = "form-control", autofocus = "autofocus", placeholder = "Cell Number" } })
@Html.ValidationMessageFor(model => model.RegForm.CellNumber, "", new { @class = "text-danger" })
