Ionic 3 set value in html template

I am trying to set a value in an Ionic 3 template from my ts file, however I am also appending css to it at the same time. I am getting this error

ERROR

Error: Uncaught (in promise): Error: No value accessor for form control with name: 'image' Error: No value accessor for form control with name: 'image'

My code is a s follows.

HTML

<img name="image" [(ngModel)]="image" id="image" src="https://openclipart.org/image/2400px/svg_to_png/247149/dual-compass-rose.png" alt="">

TS

this.image.style.transform = 'rotate(' + this.magneticHeading + 'deg)';

I am not sure why this is not working but am starting to think that angular doesn't like what I'm trying to do in the TS file by .style.transform...

Use @ViewChild to reference image tag from your DOM. Use [src] and not ngModel:

Typescript:

  @ViewChild('myImage') myImage;
  magneticHeading = '100';
  image="https://openclipart.org/image/2400px/svg_to_png/247149/dual-compass-rose.png"
  ...
  ngAfterViewInit() {
    this.myImage.nativeElement.style.transform = 'rotate(' + this.magneticHeading + 'deg)';
  }

HTML:

  <img #myImage name="image" id="image" [src]="image" alt="">

DEMO

Or to set it from HTML:

  <img #myImage [style.transform]="'rotate(' + magneticHeading + 'deg)'" name="image" id="image" [src]="image" alt="">
