角4事件中的完整日历不会在第一时间绑定

Question

我在过去的两三天里尝试过它。我按以下方式绑定fullcalendar events，但事件未在第一次反映在日历上时无法解决为什么在bindEvents()

中调用的ngOnInIt()方法发生这种情况

bindEvents() {
  this.availibiltyOptions['events'] = [];
  this.events.map((event) => {
   this.availibiltyOptions['events'].push(event);
})

OR

this.availibiltyOptions['events'] = this.events;

这是我的HTML文件：

<angular2-fullcalendar #calendar [options]="availibiltyOptions">
</angular2-fullcalendar>

这是我的TS文件

availibiltyOptions: Object = {
eventClick: (event) => {
  this.eventClick(event);
},
dayClick: (event) => {
  this.daySelection(event);
},
dayRender: (date, cell) => {
  this.cellUpdation(date, cell);
},
columnFormat: 'dddd',
viewRender: (view, element) => {
  let viewSelectedMonth = 
   parseInt(moment(view.intervalStart['_i']).format('M'));
  if (this.availibilityMonth < viewSelectedMonth) {
    this.next(view, viewSelectedMonth);
  }
  else if (this.availibilityMonth > viewSelectedMonth) {
    this.prev(view, viewSelectedMonth);
  }
}

};

ngOnInit() {

//api-call
let fromDate ='2018-02-01' 
let toDate = '2018-03-01'
this.getAvailibilty(fromDate, toDate);
}

 //AJAX-CALL
getAvailibilty(fromDate, toDate, filters?) {
 this._loader.showLoader();
 this.calendarService.getAvailibilty(fromDate, toDate, 
  filters).subscribe((res: any) => {
  this._loader.hideLoader();
  const resBody = JSON.parse(res._body);
  this.events = this.createEvents(resBody.data.availability);
  this.bindEvents();
  if (resBody.data.salutation && resBody.data.name) {
    this.dentistOrPracticeName = resBody.data.salutation + ' ' + 
    resBody.data.name;
  } else {
    this.dentistOrPracticeName = resBody.data.name;
  }

   },
    (err) => {
    this._helper.errorHandling(err, this.vcr)
    this._loader.hideLoader();
  },
  () => {
    this._loader.hideLoader();
  });
  }

现在的问题是日历上没有显示事件。
