Answer 2

On (click) you call update which I'm guessing is a function in your.ts.

If so, your.ts file can have something like this:

display: boolean = false;

/*...*/

update() {
  ...
  this.display = true;
  ...
}

Then you *ngIf=display will trigger and show whatever is contained within

Answer 3

In the click handler, update should have () , like so:

<div class="form-field col-lg-12">
   <input class="submit-btn" type="submit" value="click" (click)="update()">
</div>

<div class="form-field col-lg-12">
   <input class="submit-btn" type="submit" value="click" (click)="update()">
</div>
