如何为模型制作动作接受列表?(ASP.Net MVC 5)

我能够成功地接受数据库中的一个条目。但是，其余的条目不是来自我动态添加的字段。

这是我的Create for Sibling:

 [HttpPost]
 [ValidateAntiForgeryToken]
 public ActionResult Create(List<sibling> siblings)
    {
        if (ModelState.IsValid)
        {
            foreach(sibling x in siblings)
            {
                db.siblings.Add(x);
                db.SaveChanges();
            }
            return RedirectToAction("Index");
        }
        return View(siblings);

这是我的兄弟姐妹模型:

public partial class sibling
{
    public int sibling_id { get; set; }
    public int child_id { get; set; }
    public Nullable<int> age { get; set; }
    public string gender { get; set; }
    public virtual child child { get; set; }
}

这是我的Create.cshtml:

@model dummyApp.Schema.TestModels.sibling
@{
ViewBag.Title = "Create";
}
@section Scripts{
<script type="text/javascript">
    $(document).ready(function () {
        //var max_fields = 10; //maximum input boxes allowed
        var wrapper = $(".input_fields_wrap"); //Fields wrapper
        var add_button = $(".add_field_button"); //Add button ID
        var x = 1; //initlal text box count
        $(add_button).on("click", function (e) { //on add input button click
            e.preventDefault();
            //if (x < max_fields) { //max input box allowed
                x++; //text box increment
                $(wrapper).append('<div class="form-group">'
                                        <p>Child ID: <input type="number" name="siblings[' + x + '].child_id"/></p>       '
                                        <p>Age: <input type="number" name="siblings[' + x + '].age"/></p> '
                                        <p>Gender: <input type="text" name="siblings[' + x + '].gender"/></p>   '
                                        <a href="#" class="remove_field">Remove</a>     '
                                    </div>'); //add input box
            //}
        });
        $(wrapper).on("click", ".remove_field", function (e) { //user click on remove text
            e.preventDefault(); $(this).parent('div').remove(); x--;
        })
    });
</script>
 }
