Localization for ion-select buttons (OK and Cancel)

Ionic Framework ionic-v3
2

In docs said:

By default, the two buttons read Cancel and OK. Each button’s text can be customized using the cancelText and okText attributes:

<ion-select okText="Okay" cancelText="Dismiss">
  ...
</ion-select>

The action sheet interface does not have an OK button, clicking on any of the options will automatically close the overlay and select that value.
