Computed property does not bind to input field

[jurgenwerk]

The issue is that my date property does not bind to datepicker input when my component renders.

For demonstration purpose I added the display of actual bound property:

{{filter.value}}
{{bootstrap-datepicker value=filter.value autoclose=true class="form-control rt-input"}}

This template renders like this - input doesn't have the value displayed above, datepicker also doesn't have selected day marked:

solution: Date object

@soulim - can this be added to the docs? This is not obvious.
