jQueryUI Datepicker refresh after initialization

Question

On site I have default datepicker initializated globally for all inputs with class input-date.

$('body').on('focus', '.input-date', function () {
  $(this).datepicker({
    changeMonth: true,
    changeYear: true,
    dateFormat: 'd.m.yy'
  });
});

But sometimes I need add some other options e.g. minDate for specific element. I already tried set this option and refresh it, but without success.

var dateField = $('#date');
dateField.datepicker('option', 'minDate', new Date());
dateField.datepicker('refresh');

So for now, only way how I managed to changed it it destroy it and create new one.

var dateField = $('#date');
dateField.datepicker('destroy');
dateField.datepicker(customOptions);

Is there any better way to do it?
