I am editing a record from a list, clicking on it opens this record in a modal with user information to edit, so far so good.

My drawback is that inside the modal I am loading a service that depends on the selected user, I execute this function in the OnInitmodal but since the modal loads in my main component when I open the modal that service is empty since it was executed when loading the component main and not when loading the modal.

How could I make my function run when I open the modal and not when the component loads?

Note: the modal is in a component and my list of records in another component

Main Template:

 <app-modal modalId="editUser" modalSize="modal-lg" modalTitle="Editar Usuario - {{user.userId}}" modalIcon="ion-ios-person-outline">
  <app-edit-user [user]="user"></app-edit-user>
</app-modal>

Main component (from here I call my modal):

 onRowSelect(event) {
   this.newUser = false;
   this.user = this.cloneUser(event.data);
   $("#editUser").modal();
  }

Component Modal

  getParameters(user){
    console.log(user);
    this._userService.getParameter(user).subscribe(
      response => {
      this.userParameter = response.pagedResult.resultado;
      console.log(this.userParameter);
    }, 
      error => {
        console.log(<any>error);
      }
    );
  }

 // Desde aqui llamo la función pero como se ejecuta al cargar el componente los datos siempre vienen vacios

  ngOnInit() {
    console.log(this.user.userId);
    this.getParameters(this.user.userId);
  }

Greetings community, I am trying to pass some parameters through the headers in a post request but it generates an error, it tells me that the parameters are not being sent in the headers, does anyone know what I am doing wrong?

registerHome(user_to_registerHome){
    let params = JSON.stringify(user_to_registerHome);
    let headers = new Headers({'Content-Type': 'application/json; charset=utf-8;'},{'token':this.getToken});

    return this._http.post(this.url+'consolaseguridad-service/createUser', params, {headers: headers})
                      .map(res => res.json());
  }
