微风:将项目添加到复杂类型的数组中

我在durandal项目中有一个微风课程。类（称为"employee"）包括复杂类型的属性（名为"mainData"）。"主数据"包括名为"childrenList"的复杂类型的数组。名为"childDTO"的数组元素的复杂类型。我接受来自服务器（c#）的数据，并在客户端（javascript）中向数组添加和删除项。之后，我想将更改后的数组发送到服务器，以便保存。

我的问题是：如何向微风阵列添加项目

这是我的类定义：

员工：

         addEmployeeType(store);
    function addEmployeeType(store) {
        store.addEntityType({
            shortName: "EmployeeDTO",
            namespace: "myServer.Entities",
            autoGeneratedKeyType: AutoGeneratedKeyType.Identity,
            dataProperties: {
                Emp_no1: { dataType: DataType.Int32, isNullable: false, isPartOfKey: true },
                employeeBaseData: {
                    name: "employeeBaseData",
                    complexTypeName: "EmployeeBaseDTO:#myServer.Entities",
                    isNullable: false,
                    isPartOfKey: false
                },
                employeeMainData: {
                    name: "employeePersonalDetails",
                    complexTypeName: "EmployeePersonalDetailsDTO:#myServer.Entities",
                    isNullable: true
                }
        });
        store.registerEntityTypeCtor("EmployeeDTO", null, employeeInit);
    }

主数据：

    addEmployeeMainDataType(store);
    function addEmployeeMainDataType(store) {
        store.addEntityType({
            shortName: "EmployeeMainDataDTO",
            namespace: "myServer.Entities",
            isComplexType: true,
            dataProperties: {
                PermGroup: { dataType: DataType.Int32, isNullable: true, isPartOfKey: false },                   
                Expire_Date: { dataType: DataType.DateTime, isNullable: true, isPartOfKey: false },                  
                ChildrenList: { dataType: DataType.childDTO, isPartOfKey: false, isScalar: false }
            }
        });
        store.registerEntityTypeCtor("EmployeeMainDataDTO", null, null);
    }

子：

      addEmployeeChildType(store);
    function addEmployeeChildType(store) {
        store.addEntityType({
            shortName: "ChildDTO",
            namespace: "myServer.Entities",
            isComplexType: true,
            dataProperties: {
                name: { dataType: DataType.String, isNullable: true, isPartOfKey: false },            
                age: { dataType: DataType.Int32, isPartOfKey: false }
            }
        });
        store.registerEntityTypeCtor("ChildDTO", null, null);
    }
