ts文件里调用了updateSchema，但是页面上没有变化,

//新增页面
export const addFormSchema: FormSchema[] = [
  { label: 'id', field: 'id', component: 'Input', labelWidth: '120px', show: false },
  {
    label: '标题',
    field: 'title',
    component: 'Input',
    labelWidth: '120px',
    required: true,
  },
  {
    label: '来源',
    field: 'source',
    component: 'RadioGroup',
    labelWidth: '120px',
    componentProps: ({ formModel, formActionType }) => {
      return {
        options: [
          {
            label: '系统',
            value: 0,
          },
          {
            label: '外部',
            value: 1,
          },
        ],
        onChange: (e: any) => {
          if (e.target.value == 0) {
            // console.log('dd', e.target.value == 1);
            // formModel.receiver = undefined; //  reset city value
            const { updateSchema } = formActionType;
            updateSchema([
              {
                label: '链接',

                labelWidth: '120px',
              },
            ]);
          } else {
            console.log('aa', addFormSchema);
          }
        },

    },]
