Please explain in this code, how to call ngOnInit() again when I call another method?

ngOnInit(): void {
  this.route.params.subscribe((params: Params) => {
    this.model = this.userData;
  });
}

update() {
  this.loading = true;
  this.userService.update(this.model).subscribe(
    (data) => {
      alert('Update successful');
    },
    (error) => {
      alert('Not updated');
      this.loading = false;
    },
  );
  this.user_data();
}

If the purpose is to trigger ngOnInit() when query param is updated, then do following:

import { Router } from '@angular/router';
constructor(private router: Router) {
    this.router.routeReuseStrategy.shouldReuseRoute = () => false;
}
