Separate DateTime component for day/month/year

Hi there!
Is there a way to make it work? I would like to use different datetime components for each part of date.
That what I would achieve is something like this:

<ion-col>
    <ion-datetime name="year" displayFormat="YYYY" min="1941" max="2016" [(ngModel)]="year"></ion-datetime>
</ion-col>
<ion-col>
    <ion-datetime name="month" displayFormat="MM" [(ngModel)]="month"></ion-datetime>
</ion-col>
<ion-col>
    <ion-datetime name="day" displayFormat="DD"  [(ngModel)]="day"></ion-datetime>
</ion-col>

With the code above i can set the year, but month and day is not changing. After changing displayFormat to displayFormat=“YYYY/DD” or displayFormat=“YYYY/MM” everything is working.

Am I missing something? Thanks!

<ion-datetime [(ngModel)] =“dt” [max]="maxDateString"
pickerFormat="DD MMM YYYY"
displayFormat="DD"
placeholder=“DD”>

<ion-datetime [(ngModel)] =“dt” [max]="maxDateString"
pickerFormat="DD MMM YYYY"
displayFormat="MMM"
placeholder=“MM”>

<ion-datetime [(ngModel)] =“dt” [max]="maxDateString"
pickerFormat="DD MMM YYYY"
displayFormat="YYYY"
placeholder=“YYYY”>
