AngularJS and input type = date, how to format model data?

i have following form input which i'm trying to fill by scope data:

<input type="date" name="editCallForm.date"  ng-model="editCallForm.date">

I tried a few combination of date formatting, for example:

moment($rootScope.formData.date).format('DD/mm/YYYY');

But without luck (for time input is it working without problems).

What is the right format for this type of the input?

Thanks for any help.
