typescript - Angular 2: How to use JavaScript Date Object with NgModel two way binding

Question

I'm working with Angular 2 and I have this code:

JS, this code initiates the employee-variable for the template:

handleEmployee(employee : Employee){
        this.employee = employee;
        this.employee.startDate = new Date('2005/01/01');
        console.log(this.employee);
    }

Template:

...
<div>
    <label>Start date: </label>
    <input [(ngModel)]="employee.startDate" type="date" name="startDate"/>
  </div>
  <div>
...

Other data like firstname is displayed correctly. But for the date I just get:

mm/dd/yyyy

In the input element, which should be a date.

How can I do this?

UPDATE:

StackBlitz

when I wrote this answer DatePipe did not exist, now you can just do this

<input [ngModel]="startDate | date:'yyyy-MM-dd'" (ngModelChange)="startDate = $event" type="date" name="startDate"/>

You need to convert date object in the input type="date" format which is yyyy-mm-dd, this is how it will work

Template:

<input [(ngModel)]="humanDate" type="date" name="startDate"/>

Component (TS):

export class App {
  startDate: any;

  constructor() {
    this.startDate = new Date(2005, 1, 4);
  }

  set humanDate(e){
    e = e.split('-');
    let d = new Date(Date.UTC(e[0], e[1]-1, e[2]));
    this.startDate.setFullYear(d.getUTCFullYear(), d.getUTCMonth(), d.getUTCDate());
  }

  get humanDate(){
    return this.startDate.toISOString().substring(0, 10);
  }
}
