ASP.NET MVC [Обязательно] не вызывает

Question

Как указано в названии, поле «Обязательное» не запускается.

Это мой ViewModel класс его имя SignUpForm.cs

public class SignUpForm 
{ 
    [Required] 
    [StringLength(100,ErrorMessage="You must enter a your firstname!", 
    MinimumLength = 1)] 
    public string FirstName { get; set; } 
    [Required] 
    [StringLength(100, ErrorMessage = "You must enter a your surname!", 
    MinimumLength = 1)] 
    public string SurName { get; set; }  
} 

Это мое мнение Бритва! Имя зрения Step2.cshtml

@model MvcApplication2.Models.ViewModel.SignUpForm 
@{ 
ViewBag.Title = "Step2"; 
} 

<div id="content-header"> 
<h1 class="title">Complete your registration</h1> 
</div> 
<div id="content-area"> 
    <h4>Fill in the form below to complete your registration 
    </h4> 
@using(Html.BeginForm("testar","Interested", FormMethod.Post)) 
{ 


<h3>Personal information</h3> 
<p class="app-label">Surname<span class="requiredField">*</span></p> 
<div class="editor-label"> 
    @Html.EditorFor(model => model.FirstName) 
    @Html.ValidationMessageFor(m => m.FirstName) 
</div> 
<p class="app-label">Surname<span class="requiredField">*</span></p> 
<div class="editor-label"> 
    @Html.EditorFor(model => model.SurName) 
    @Html.ValidationMessageFor(m => m.SurName) 
</div> 
}
