Bind button click to service method angular2+

I have a logout method in my auth service. I'm trying to call it from a component, however this does not seem to be working.

template

<a class="dropdown-item" (click)="auth.logout()">Logout</a>

component

import { AuthService } from '../../_services/auth.service';

constructor(
    public auth:AuthService
  ) {}

auth service

  public logout() {
    return this.http.post<any>(this.apiHost+'/users/logout', {})
    .map(() => {
      localStorage.removeItem('currentUser');
      this.router.navigate(['/']);
      this.alertService.warning('You have been logged out.', true)
    })
    .catch(this.handleError);
  }

What am I doing wrong? Do I need to call a local function instead of calling auth directly from the template?

You can returning an Observable from logout function. But calling this function don't means subscribe from the Observable.

Try to add subscribe() to subscribe it.

public logout() {
  return this.http.post<any>(this.apiHost+'/users/logout', {})
    .map(() => {
      localStorage.removeItem('currentUser');
      this.router.navigate(['/']);
      this.alertService.warning('You have been logged out.', true)
    })
    .catch(this.handleError)
    .subscribe();
}
