`this` not set to component instance when creating component programatically

I have a directive that reads src attribute and appends a DynamicComponent. It also sets an input property of DynamicComponent.

@Directive({
  selector: '[appDynamic]'
})
export class InjectDirective {
  @ViewChild('container', {read: ViewContainerRef}) container: ViewContainerRef;

  constructor(
    private element: ElementRef,
    private viewContainerRef: ViewContainerRef,
    private componentFactoryResolver: ComponentFactoryResolver
  ) { }

  ngOnInit(){
    const nativeElement = this.element.nativeElement;
    const src = nativeElement.getAttribute('src');

    if (src) {
      const componentFactory = this.componentFactoryResolver.resolveComponentFactory(DynamicComponent);
      const componentRef = this.viewContainerRef.createComponent(componentFactory);
      componentRef.instance.mediaPath = src;
      const parent = this.element.nativeElement.parentElement;
      parent.insertBefore(componentRef.location.nativeElement, this.element.nativeElement.nextSibling)
    }
  }
}

The injection happens, but I can't read mediaPath in the DynamicComponent due to this not being set to the right value. this is an object that only has property __ngContext__.

export class DynamicComponent implements OnInit {

  @Input() mediaPath:string;
  constructor() { }

  ngOnInit(): void {
  }

  openSection(event){ // click event
    console.log(this); // this does not refer to instance of DynamicComponent
    console.log(this.mediaPath); // this.mediaPath is undefined
  }

}

What is the correct way of creating a component dynamically and also passing values to the component properties? I am using angular 11.

UPDATED to Angular 14. Still the same problem:

@Directive({
  selector: '[appInject]'
})
export class InjectDirective {
  @ViewChild('container', {read: ViewContainerRef}) container: ViewContainerRef;

  constructor(
    private element: ElementRef,
    private viewContainerRef: ViewContainerRef,
  ) { }

  ngOnInit(){
    const nativeElement = this.element.nativeElement;
    const src = nativeElement.getAttribute('src');

    if (src) {
      const componentRef = this.viewContainerRef.createComponent(DynamicComponent);
      componentRef.setInput("mediaPath",src)
      const parent = this.element.nativeElement.parentElement;
      parent.insertBefore(componentRef.location.nativeElement, this.element.nativeElement.nextSibling)
    }
  }
}


export class DynamicComponent implements OnInit {

  @Input() mediaPath:string;
  constructor() { }

  ngOnInit(): void {}
  
  openFindSimilarSection(event){
    console.log(this); // only has __ngContext__ property
    console.log(this.mediaPath); // this is undefined
  }
}

//used like this:

  <img [src]="dynamically.added.path" appInjectFindSimilar>

Try using setInput method to pass in the input.

  const componentRef =
    this.viewContainerRef.createComponent(componentFactory);
  componentRef.setInput('mediaPath', src);

Full Code:

import {
  Component,
  Input,
  Directive,
  ViewChild,
  ViewContainerRef,
  ComponentFactoryResolver,
  ElementRef,
  Renderer2,
  Attribute,
} from '@angular/core';
import { bootstrapApplication } from '@angular/platform-browser';

@Component({
  selector: 'dynamic-component',
  template: `dynamic component`,
})
export class DynamicComponent {
  @Input() mediaPath!: string;
  constructor() {}

  ngOnInit(): void {
    // click event
    console.log(this); // this does not refer to instance of DynamicComponent
    console.log(this.mediaPath); // this.mediaPath is undefined
  }

  openSection(event: any) {}
}

@Directive({
  selector: '[appDynamic]',
})
export class InjectDirective {
  @ViewChild('container', { read: ViewContainerRef })
  container!: ViewContainerRef;

  constructor(
    private element: ElementRef,
    private viewContainerRef: ViewContainerRef,
    private componentFactoryResolver: ComponentFactoryResolver,
    private renderer: Renderer2,
    @Attribute('src') public src: string
  ) {}

  ngOnInit() {
    const nativeElement = this.element.nativeElement;

    if (this.src) {
      const componentFactory =
        this.componentFactoryResolver.resolveComponentFactory(DynamicComponent);
      const componentRef =
        this.viewContainerRef.createComponent(componentFactory);
      componentRef.setInput('mediaPath', this.src);
      // componentRef.instance.mediaPath = src;
      const parent = this.element.nativeElement.parentElement;
      parent.insertBefore(
        componentRef.location.nativeElement,
        this.element.nativeElement.nextSibling
      );
    }
  }
}

@Component({
  selector: 'app-root',
  imports: [InjectDirective],
  template: `
    <img appDynamic [src]="'test'"/>
  `,
})
export class App {
  name = 'Angular';
}

bootstrapApplication(App);
