Setting value to DD/MM/YYYY does not work

My model returns data in dd/mm/yyyy format. Passing this value of ember-pikaday does not work and the input is blank.

```handlebars
{{#each parent.child_list as |child index|}}
...
{{pikaday-input firstDay=0 format="DD/MM/YYYY" yearRange="2010,currentYear" name="child_dob[]" id=(concat 'child_dob-' index) value=child.dob placeholder="hh/bb/tttt"}}
...
{{/each}}
```

The `child.dob` value looks something like this `18/07/2017`. I even try to put a static value in there and the result is the same. It works when i changed it into `07/18/2017` (mm/dd/yyyy).
