Force blur() on ion-input by Angular reference in Ionic 3

Ionic Framework ionic-v3
1

Hey, guys.

Does anybody know how to force blur on ion-input element by Angular reference?
I was searching the forum and found one question which seems like something I am looking for: How to force Blur on ion-input

Is this solution OK? Because for me it looks hacky.

Here is the code block which my application uses:

<form (ngSubmit)="ask(question)">
      <ion-item id="person-info">
        <ion-label stacked>Some label</ion-label>
        <ion-input type="text" required #question></ion-input>
      </ion-item>

      <div class="ask-person-button">
        <button ion-button block type="submit">Ask person</button>
      </div>
</form>

And in .ts file:

import {Component, OnInit} from '@angular/core';
import {NavParams, AlertController} from 'ionic-angular';

@Component({
  selector: 'ask-person',
  templateUrl: 'ask-person.html'
})
export class AskPersonPage implements OnInit {
  ask(input) {
    // can I use something like input.blur() ?
  }
}
