Embedded datepicker behaves different

Embedded datepicker behaves different

Hi,

please have a look at the following configuration:  http://codepen.io/anon/pen/Kmrex

I would like to know why the datepicker component selects a date when it is embedded in the site? Is that the desired behaviour when using the component with the option  minDate: 1 ?

If it is the desired behaviour, any ideas how to avoid this? I would like my users to choose a date from a "clean" datepicker.

Thanks,
Markus
