ng-alain 表单组件的传参问题

Question

代码如下，我希望title可以根据@input内穿的参动态改变，怎么实现呢？

 @Input()
  id: string;
  pageTitleName: string;

  @ViewChild('sf', { static: false }) sf: SFComponent;
  formData = {};
  schema = {
    properties: {
      creator: {
        type: 'string',
        title: '名称',
      },
      gender: {
        type: 'string',
        title: '性别',
        ui: {
          widget: 'radio',
          asyncData: () =>
            of([
              { label: '男', value: 'Man' },
              { label: '女', value: 'Woman' },
            ]).pipe(delay(100)),
          grid: {
            span: 12,
          },
        } as SFRadioWidgetSchema,
        default: '',
      },
      type: {
        type: 'string',
        title: '记录类型',
      },
      title: {
        type: 'string',
        title: this.pageTitleName,
      },
      description: {
        type: 'string',
        title: '详情',
      },
      startDate: {
        type: 'string',
        title: '开始时间',
        format: 'date',
      },
      endDate: {
        type: 'string',
        title: '结束时间',
        format: 'date',
      },
    },
    ui: {
      spanLabelFixed: 70,
      grid: {
        span: 24,
      },
    },
    required: ['title', 'creator', 'gender', 'type', 'description', 'startDate', 'endDate'],
  };
  layout = 'horizontal';

取不到值。已找到解决方法，在ngoninit中把对象属性重写就好了。谢谢大家
