Getting null values while Remote Validating CurrentPassword - html

Question

I have a currentPassword property in my changePasswordViewModel and i want to validate it on client side using Remote attribute. this is my model
public class PatientPasswordChangeViewModel
{
public int id { get; set; }
[Required(ErrorMessage ="field is required")]
[DataType(DataType.Password)]
[Remote("IsCorrectPassword", "Patient", ErrorMessage ="Password is incorrect")]
[Display(Name ="Current Password")]
public string OldPassword { get; set; }
[Required(ErrorMessage ="field is required")]
[StringLength(100, ErrorMessage = "The {0} must be atleast {2} characters long", MinimumLength = 6)]
[DataType(DataType.Password)]
[Display(Name = "New Password")]
public string NewPassword { get; set; }
[Required(ErrorMessage ="field is required")]
[DataType(DataType.Password)]
[Compare("NewPassword",ErrorMessage ="Password Does Not Match")]
[Display(Name = "Confirm Password")]
public string ConfirmNewPassword { get; set; }
}
this is RemoteValidation Code in the controller
public JsonResult IsCorrectPassword([Bind(Prefix = "PatientPasswordChangeViewModel.OldPassword")] string OldPassword, [Bind(Prefix = "PatientPasswordChangeViewModel.id")] int id)
{
var getUserName = context.Patients.Where(q => q.p_id == id).Select(q => q.UserName).FirstOrDefault();
var getPassword = context.SiteUsers.Where(q => q.UserName == getUserName).Select(q => q.PasswordHash).FirstOrDefault();
bool status;
if (PasswordHashManager.ValidatePassword(OldPassword, getPassword))
{
status = true;
}
else
{
status = false;
}
return Json(status, JsonRequestBehavior.AllowGet);
}
And this is the View Code
<section class="password_change-body">
<h2 id="passheading">Change Password</h2>
#using (Html.BeginForm("ChangePassword", "Patient", FormMethod.Post))
{
#Html.AntiForgeryToken()
<div class="form-horizontal">
#Html.HiddenFor(model => model.id)
<hr />
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
<div class="form-group">
#Html.LabelFor(model => model.OldPassword, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.OldPassword, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.OldPassword, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.NewPassword, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.NewPassword, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.NewPassword, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.ConfirmNewPassword, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.ConfirmNewPassword, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.ConfirmNewPassword, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="change" class="btn btn-primary" />
</div>
</div>
</div>
}
</section>
I've tried
public JsonResult IsCorrectPassword([Bind(Prefix = "PatientPasswordChangeViewModel")] string OldPassword, [Bind(Prefix = "PatientPasswordChangeViewModel")] int id)
public JsonResult IsCorrectPassword(PatientPasswordChangeViewModel model)
although i'm getting the password value but value for property id is always null. how can i get the value of id.
EDIT
I got it working by using AdditionalValues in Remote Attribute used it in my method.
[Remote("IsCorrectPassword", "Patient", ErrorMessage ="Password is incorrect",AdditionalFields ="id")]
and in my controller method
public JsonResult IsCorrectPassword(string OldPassword, int id)
