How to validate a duplicate post request from a form in MVC - asp.net-mvc

Question

I am having an form which insert a record whenever a post request is made,but the problem is that if someone clicks submit button more than 1 times than duplicate post request are made and at the end same records are getting inserted. I dont want to check that the record is already present or not because the record would be different always. I tried using ValidateAntiForgeryToken filter in controller but it is failing to validate the requests, Below is my View Code.
#using (Html.BeginForm("Create", "Home",FormMethod.Post,new { onkeydown = "return event.keyCode!=13" }))
{
#Html.AntiForgeryToken()
<div class="right-col">
#Html.TextBoxFor(model => model.Name, new { placeholder = "Name", #class = "small-box" })
</div>
<div class="left-col">Email Id :</div>
<div class="right-col">
#Html.TextBoxFor(model => model.EmailId, new { placeholder = "Email Id", #class = "small-box",id="resumeemailid" })
#Html.ValidationMessageFor(model => model.EmailId)
</div>
<div class="left-col">Address :</div>
<div class="right-col">
#Html.TextAreaFor(model => model.Address, new { placeholder = "Address", #class = "small-box" })
</div>
<div class="buttons resume-threebutton">
<input type="submit" id="register-button" class="gradient-btn" value="#T("Account.Passport.Register.Button.Upload", "Upload")" name="Command" />
<input type="submit" id="register-button" class="gradient-btn" value="#T("Account.Passport.Button.UploadandAdd", "Upload And Add New")" name="Command" />
<input type="button" id="register-button" class="gradient-btn" value="#T("Account.Passport.Register.Button.Cancel", "cancel")" name="register-button" onclick="location.href='#Url.Action("SelectTemplate", "CustomerTemplate")'" />
</div>
}
and below is my controller Post method
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create(ProductModel model)
{
//To do add the product here...
}
