How can I write a submit form using bootstrap modal? - asp.net-mvc

Question

I'm using a bootstrap modal in asp.net mvc 5. But I'm having a problem with modal which I can't submit data. I have had call a _regiserPartial View form my _Layout (Master Page).
my controller:
[HttpPost]
public ActionResult Register(UserViewModel model)
{
var userViewModel = Mapper.Map<UserViewModel, User>(model);
if (ModelState.IsValid)
{
userViewModel.Status = true;
_userService.InsertUser(userViewModel);
model = new UserViewModel();
}
return View(model);
}
my _registerPrtial View:
#model HoiCode.Web.Models.Users.UserViewModel
<form class="form-horizontal">
<div id="registerModal" class="modal fade">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title">Resgister</h4>
</div>
#using (Html.BeginForm("Register", "User", FormMethod.Post))
{
#Html.AntiForgeryToken()
<div class="modal-body">
<div class="form-group">
<label class="col-sm-4 control-label">#Html.LabelFor(m => m.Email)</label>
<div class="col-sm-8">
#Html.TextBoxFor(m => m.Email, new { #type = "email", #class = "form-control" })
</div>
</div>
<div class="form-group">
<label class="col-sm-4 control-label">#Html.LabelFor(m => m.Password)</label>
<div class="col-sm-8">
#Html.PasswordFor(m => m.Password, new { #class = "form-control" })
</div>
</div>
</div>
<div class="modal-footer">
<button type="submit" class="btn btn-primary">Submit</button>
</div>
}
</div>
</div>
</div>
<script>
$(document).ready(function () {
$('.launchRegisterModal').click(function () {
$('#registerModal').modal({
keyboard: false
});
});
});
</script>
my _layout: I'll call _registerPartial from here
Register
