angular2中引用kendoUI-combobox進行過濾

*
引用kendoUI-combobox組件，並過濾
定義組件裏需要用到的屬性：
allowCustom：是否允許用戶輸入不在數據集中的值，默認false
data：數據集
filterChange：定義過濾方法
filterable：是否過濾
valuePrimitive：是否原始類型數據
ngStyle：樣式

<kendo-combobox
      [allowCustom]="false"
      [data]="filterData"
      (filterChange)="modelChanged.next($event)"
      [(ngModel)]="value"
      [filterable]="true"
      [valuePrimitive]="true"
      [ngStyle]="ngStyle"
    ></kendo-combobox>

  public options: any[];

  public ngStyle = {'width': '100%'};

  public filterData = [];

  modelChanged: Subject<object> = new Subject<object>();

  handFilter(value) {
    let datas = this.options;
    this.filterData = [];
    if (value)
      datas = datas.filter(i => i.indexOf(value) != -1);
      datas.forEach(i => {
      this.filterData.push(i);
    });
  }

  ngOnInit() {
    this.Svc.query("基礎代碼#地區").then(data => {
      this.options = [];
      data.forEach(m => {
        this.options.push(m["地區名稱"]);
      })
      this.filterData = this.options;
    });
    this.modelChanged.debounceTime(300).distinctUntilChanged().subscribe(m => this.handFilter(m));
  }
