Expected behavior

inside onRemoving I don't have access to external variables like this.http, it is undefined

<tag-input [onRemoving]="onRemoving">

constructor(private http: HttpClient) {
}

public onRemoving(tag: TagModel): Observable<TagModel> {
        console.log(this.http);
        return this.http.delete<TagModel>('/api/upload/' + tag.id).pipe(map(r => {
            return tag;
        }));
 }
