    $scope.RemoveBankCtrl = true;
    $scope.ArrBankCtrls = [{

                $scope.RemoveBankCtrl = true;
            }
        }
    }

    //#region Bind Bank Name ddl
    $scope.ArrBankCtrls[0].BankName = "--Select Bank--";
    VendorService.postData(strVenUrl + "/GetBank").then(function (data) {

            $scope.bankName = data;
        }
    })
    // #endregion

    // #endregion

Controller.cs Code

 #region GetBank

        public ActionResult GetBank()
        {
            dynamic bank = null;
            try
            {
                bank = vendor.Bank();
            }
            catch (Exception ex)
            {
                ExceptionError(ex.Message);
            }
            return Json(bank, JsonRequestBehavior.AllowGet);
        }

        #endregion


        [HttpPost]
        public ActionResult InsertBankDetails(List<BankDetails> bankDetails)
        {
            //Your code
            return RedirectToAction("BankDetails");
        }

you must have used somewhere collections, bind that collection in the ng-repeat directive, on the button click and add simply remove and add an item from the collection
