Whenever I try to call a method from another Component in the Angular, it returns me an error. Below is my TypeScript code:

Component1: 

  metodoAlertar() {
    console.log('bls')
  }

Component2: 

  cpmn: Component1Component;
  constructor() { 
  }
  ngOnInit() {
    this.cpmn.metodoAlertar();
  }

If it's a child element you have to sweat the ViewChild to get the reference. 

<child-tag #varName></child-tag>

@ViewChild('varName') someElement;

ngAfterViewInit() {
  someElement...
}
