click the button and increase number through component - angular

Hej, I'm having having a problem with button which should increase number +=1 and display in the view this number.

app.component.ts

import { Component } from '@angular/core';
import { CounterService } from '../common/services/counter.service';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.sass']
})
export class AppComponent {
constructor(private counterService: CounterService) {}
get count() {
    return this.counterService
  }
  set count(count){
    this.counterService.count += 1;
  }
}

counter.service

export class CounterService {
count = 0;
}

app.component.html

<div class="container">
  <div>
    <p> {{ counterService.count }}</p>
    <button  (click)="count()" class="btn btn-default form-control increaseBtn">INCREASE</button>
  </div>
</div>

I can display 0 but when I'm stacked with incrementation. Thx in advance!
