Angular2 ngModelChange previous value

Is there a way to get the previous(last) value of a field on ngModelChange? What I have goes something like this

HTML

<input type="text" [(ngModel)]="text" (ngModelChange)="textChanged($event)">

Handler

private textChanged(event) {
    console.log('changed', this.text, event);
}

What I get is

changed *newvalue* *newvalue*

Of course I can keep the older value using another variable, but is there a better way?

Solution

  • So found kinda weird(at least for me) possible solution for this with least changes in the code in question. So on assigning the (ngModelChange) attribute before [(ngModel)] what I get is following with the same handler:

    changed *older value* *new value*

    I get the new value in this.textlike so:

    setTimeout(() => console.log(this.text), 0);
