Unable to Autofocus Input

Ionic Framework ionic-v3
1

I have a regular input ( not an ionic input ) inside of a modal. I want to autofocus it after the modal slides up, but the code I thought would work does not, the input does not focus and the keyboard does not show up.

HTML

<input #test id="test"
              (touchstart)="focusInput()"
              (keypress)="enterPress($event)"
              maxlength="20"
              class="pure-input"
              type="text"
              placeholder="Test...">

Component:

I have tried this in a setTimeout or just by itself

ngOnInit() {
    let ele = document.getElementById('test');
    ele.focus();
  }

Also tried calling this

public focusInput() {
    this.testInput.nativeElement.focus();
  }

Neither works on the input
