Simple Register page unable to post

Hi Guys,

I have simple register page and unable to save to db using ASP.NET core MVC, below is my code

  [HttpPost]
        public IActionResult Index(Registration registration)
        {
            if(ModelState.IsValid)
            {
                _context.Registration.Add(registration);
                _context.SaveChanges();
            }
            return View(registration);
        }

@model GOMLIB.Models.Registration<div class="row"><div class="col-xl-12"><div class="card"><div class="card-body"><h4 class="header-title text-yellow">REGISTER WITH US</h4>
                @*<p class="sub-header">
                        Easily extend form controls by adding text, buttons, or button groups on either side of textual inputs, custom selects, and custom file inputs</p>*@

                @using (Html.BeginForm())
                {
                    <div class="form-group mb-1 mt-3"><div class="input-group"><input type="email" class="form-control" placeholder="Enter email address" required parsley-type="email" aria-label="Enter email address"><div class="input-group-append"><input class="btn btn-info waves-effect waves-light" type="submit" value="Register" /></div></div></div>
                }</div></div></div></div>

using System;
using System.Collections.Generic;
using System.Text;

namespace GOMLIB.Models
{
    public partial class Registration
    {        
        public int Registrationid { get; set; }
        public string Email { get; set; }
        public DateTime Createddate { get; set; }
    }
}
