I can not send my data from a dynamic table in C # mvc

Good, I have a question. I can not send the data entered by the user in my pivot table to my MVC controller and C # in my view I have the following:

Function that creates the Dynamic table:

function fn_agregar() {
   cadena = "<tr>";
   cadena = cadena + "<td><input style='font - size: 20px; font - weight: 700;' class='form - control' type='text' name='COD_CLASIFICADOR[]' value='" + alias("#COD_CLASIFICADOR").val() + "' readonly required></td>";
   cadena = cadena + "<td><input style='font - size: 20px; font - weight: 700;' class='form - control' type='text' name='COD_ITEM[]' value='" + alias("#COD_ITEM").val() + "' readonly required></td>";
   cadena = cadena + "<td><input style='font - size: 20px; font - weight: 700;' class='form - control' type='text' name='NOMBRE[]' value='" + alias("#NOMBRE").val() + "' readonly required></td>";
   cadena = cadena + "<td><input style='font - size: 20px; font - weight: 700;' class='form - control' type='text' name='VALOR_UNITARIO[]' value='" + alias("#VALOR_UNITARIO").val() + "' readonly required></td>";
   cadena = cadena + "<td><input style='font - size: 20px; font - weight: 700;' class='form - control' type='text' id='CANTIDAD2' name='CANTIDAD[]' value='" + alias("#CANTIDAD").val() + "' readonly required></td>";
   cadena = cadena + "<td><input style='font - size: 20px; font - weight: 700;' class='form - control' type='text' name='VALOR_BRUTO[]' value='" + alias("#VALOR_BRUTO").val() + "' readonly required></td>";
   cadena = cadena + "<td><input style='font - size: 20px; font - weight: 700;' class='form - control' type='text' name='VALOR_TOTAL[]' value='" + alias("#VALOR_TOTAL").val() + "' readonly required></td>";
   cadena = cadena + "<td><a class='elimina'><button class='btn btn-danger' type='button'><span class='fa fa-remove'></span></button></a></td>";
        alias("#detalles tbody").append(cadena);
   fn_eliminar();
   sumar();
   limpiar();    
};

function limpiar() {
   document.getElementById("COD_CLASIFICADOR").value = "";
   document.getElementById("COD_ITEM").value = "";
   document.getElementById("NOMBRE").value = "";
   document.getElementById("VALOR_UNITARIO").value = "";
   document.getElementById("CANTIDAD").value = "";
   document.getElementById("VALOR_BRUTO").value = "";
   document.getElementById("VALOR_TOTAL").value = "";
}

function fn_eliminar() {
   alias("a.elimina").click(function () {
      valor = alias(this).parents("tr").find("td").eq(5).html();
         alias(this).parents("tr").fadeOut("normal", function () {
         alias(this).remove();
         restar();
      })
   });
};

The function that sends the data

//Collect Multiple Order List For Pass To Controller
   alias("#saveOrder").click(function (e) {
      debugger;
      e.preventDefault();

      // var orderArr = [];
      // orderArr.length = 0;

      var orderArr = new Array;
      alias.each(alias("#detalles tbody"), function () {
         orderArr.push({
            COD_CLASIFICADOR: alias(this).find('td:eq(0)').html(),
            COD_ITEM: alias(this).find('td:eq(1)').html(),
            VALOR_UNITARIO: alias(this).find('td:eq(3)').html(),
            CANTIDAD: alias(this).find('td:eq(4)').html(),
            VALOR_BRUTO: alias(this).find('td:eq(5)').html(),
            VALOR_TOTAL: alias(this).find('td:eq(6)').html()
         });
      });

//After Click Save Button Pass All Data View To Controller For Save Database
   function saveOrder(data) {
      return alias.ajax({
         contentType: 'application/json; charset=utf-8',
         dataType: 'json',
         type: 'POST',
         url: "/Cotizacion/Create",
         data: data,
         success: function (result) {
            alert(result);
            location.reload();
         },
         error: function () {
            alert("Error!")    }
         });
      };

      var data = JSON.stringify(orderArr);

      alias.when(saveOrder(data)).then(function (response) {
         console.log(response);
      }).fail(function (err) {
         console.log(err);
      });
   });

My controller

public JsonResult Create(CB_COTIZACION cB_COTIZACION, Detalle[] data)
{
   foreach (var item in data)
   {
      if (ModelState.IsValid)
      {
         cB_COTIZACION.NUM_COTIZACION = cb_cotizazion;
         cB_COTIZACION.COD_CLIENTE = cB_COTIZACION.COD_CLIENTE;
         cB_COTIZACION.COD_VENDEDOR = cB_COTIZACION.COD_VENDEDOR;
         cB_COTIZACION.VALOR_BRUTO = item.VALOR_BRUTO;
         cB_COTIZACION.VALOR = item.VALOR_TOTAL;
      }
    );
    db.CB_COTIZACION.Add(cB_COTIZACION);

In the Model

{
   public class MVCJsonPost
   {
   }

   public class Detalle
   {
      public string COD_CLASIFICADOR { get; set; }
      public string COD_ITEM { get; set; }
      public decimal VALOR_UNITARIO { get; set; }
      public int CANTIDAD { get; set; }
      public decimal VALOR_BRUTO { get; set; }
      public decimal VALOR_TOTAL { get; set; }
   }
}
