Angular input type text onfocus date picker > value

I've got a dateTime that needs to edited. A dateTime picker for angular/ionic is non-existent, so I've split the field in a date and a time field. To be able to use a placeholder and do some localization formatting (read; date formatting) I have used the type=text and onfocus="this.type='date';" trick.

This gives me esthetically what I want, until I click the object. It show a Date picker, but with the current date, not the value I use in the placeholder. Also value= won't do the trick. Any thoughts on this?
