nouislider with angular2 - set is not a function

I am using a 2-handle nouislider. It works great but when I try to update the handle positions from the code, I keep getting the error: set is not a function. What am I missing?

//HTML

<nouislider #mrangeslider [connect]="true" [step]=".05"
          [(ngModel)]="sliderMRangeSel" (change)="updateSliderM($event)"
          [min]="sliderMBounds[0]"
          [max]="sliderMBounds[1]">
</nouislider>

//in main module

import { NouisliderModule } from 'ng2-nouislider';

// in component

@ViewChild("mrangeslider") mSliderEl : ElementRef;
sliderMBounds = [1,2];
sliderMRangeSel = [1.25,1.75];
...
this.sliderMRangeSel = [1.25,1.75];
this.mSliderEl.set(this.sliderMRangeSel); // trying to update the handles

In browser too I get the same:

> this.mSliderEl.set([1.25,1.75])
  VM492:1 Uncaught TypeError: this.mSliderEl.set is not a function
// but there is a `set` property defined, no observers
> this.mSliderEl.set
  EventEmitter {_isScalar: false, observers: Array(0), closed: false,
                   isStopped: false, hasError: false, …}

Obviously I have missed some step. I am using nouislider v13.1.0 with angular v7.1.0 running on chrome browser Windows 10.

Thanks

Solution

Since the template reference variable #mrangeslider is set on the slider component, the default value given by @ViewChild() is the NouisliderComponent class instance. I assume that this is what you want. With it, you can access the slider properties and methods. If needed, you could get a reference to the component HTML host element by setting the read property to ElementRef:

@ViewChild("mrangeslider") mSliderComp: NouisliderComponent;
@ViewChild("mrangeslider", { read: ElementRef }) mSliderEl: ElementRef;

That being said, since sliderMRangeSel is bound with [(ngModel)], the component should adjust automatically when changing the range values, without having to call a method of the component.

setSliderRange() {
  // The slider will adjust after selecting the range
  this.sliderMRangeSel = [1.15, 1.9];
}

See this stackblitz for a demo.
