Angular 5, Set Component's Template From Database, And Render Context Data

Question

I am trying to load a component's template dynamically from database, what I have is the following HTML Template

<h1>{{tname}}</h1>

I tried two methods one mentioned in Angular official Doc and second using createEmbeddedView() called on ViewContainerRef I do get the template results withh1 tag applied but the template is not rendered. I get {{tname}}

I have inside the component's template:

<div #target></div>
<ng-template #template>
    <div [innerHTML]="templateString"></div>
</template>

I also tried:

<div #target></div>
<ng-template #template let-tname="fromContext">
    <div [innerHTML]="templateString"></div>
</template>

My questions are:

• How would I render the template, with supplied data?
• Can I set the Component's template dynamically i.e the value of template supplied to the @Component decorator?

Edit Component's Code:

@Component({
  selector: 'app-print-receipt-template-preview',
  templateUrl: './print-receipt-template-preview.component.html',
  styleUrls: ['./print-receipt-template-preview.component.scss']
})
export class PrintReceiptTemplatePreviewComponent implements OnInit {
   private _tmp:string;
   private _data:any;

   @Input()
   set template(v:string) {
     if (v) {
       this._tmp = v;
       this.initTemplate()
     }
   }

   get template() {
     return this._tmp;
   }

   @Input()
   set saleData(v:any) {
     this._data = v;
   }

   get saleData() {
     return this._data;
   }

   @ViewChild('receiptContainer', {read: ViewContainerRef}) private target: ViewContainerRef;

   @ViewChild('template',{read: TemplateRef}) private tmp: TemplateRef<any>;

   constructor(private componentResolver: ComponentFactoryResolver) { }

   ngOnInit() {
   }

   initTemplate() {
     // let cmp = PrintReceiptTemplateComponent;
     // let fac = this.componentResolver.resolveComponentFactory(cmp);
     this.target.clear();
     let componentRef = this.target.createEmbeddedView(this.tmp, {saleData: this._data});
     // let instance:any = componentRef.instance;
     // instance.data = this._data;
    // instance.template = this._tmp;
   }
}
