我正在使用Angular 2(TypeScript).

我想为新的选择做点什么,但是我在onChange()中得到的东西总是最后选择.我怎样才能获得新的选择？

<select [(ngModel)]="selectedDevice" (change)="onChange($event)">
    <option *ngFor="#i of devices">{{i}}</option>
</select>

onChange($event) {
    console.log(this.selectedDevice);
    // I want to do something here for new selectedDevice, but what I
    // got here is always last selection, not the one I just select.
}
