How create an input box having a + and - button in Ionic

How I can create an input box having a + and - button. Clicking upon which user can change the quantity of product selected, like this screen:

Here's a quickly thrown together example for Ionic 2. If you are using Ionic 1 you should be able to adapt it pretty easily.

You just need a couple controller/class functions to increment and decrement, then call those on tap from the buttons. This example covers just one button, so something like this wrapped in an ngFor or a <ion-list>

page.ts:

private currentNumber = 0;
constructor () { }

private increment () {
  this.currentNumber++;
}

private decrement () {
  this.currentNumber--;
}

page.html:

<ion-icon name="remove-circle" (click)="decrement()">
{{currentNumber}}
<ion-icon name="add-circle" (click)="increment()">
