Set horizontal scroll position - Ionic 3

Question

I'm trying to change the scroll position of an ion-scroll element but don't getting.. this is what I have tried:

ts

import { Component, ViewChild, ElementRef } from "@angular/core";

 @ViewChild("scroller", { read: ElementRef })
  private scroller: ElementRef;

html

 <ion-scroll #scroller scrollX="true" style="height: 21px; white-space: nowrap">
  <div>... </div>
 </ion-scroll>

This works

  this.scroller.nativeElement.style.background = "blue";

This doesn't work

  this.scroller.nativeElement.scrollLeft = this.scroller.nativeElement.scrollWidth;
