How to dynamically change minDate and maxDate bounds in datetimepicker?

Question

JavaScript

Hello.
i have 2 datetimepicker on form with and by
define them in document.create like this

$(document).ready(function()
    {
        $('#datetime_from').datetimepicker(
            {
                maxDate: tdatetime,
                onSelect: function(selected,evnt) {
                    updateDateTime_from(selected);
                }
            }
        ).datetimepicker("setDate", fdatetime);

        $('#datetime_to').datetimepicker(
            {
                minDate: fdatetime,
                onSelect: function(selected,evnt) {
                    updateDateTime_to(selected);
                }
            }
        ).datetimepicker("setDate", tdatetime);
});

outside I define updateDateTime_from, updateDateTime_to
in order to process the change of date and time selection in them I try to adjust the minDate and maxDate options

function updateDateTime_from(value){
$("#datetime_to").datetimepicker("option", "minDate", value);
};
function updateDateTime_to(value){
$("#datetime_from").datetimepicker("option", "maxDate", value);
};

in fact, dynamically transferring to value passes correctly, BUT the change of minDate and maxDate does not occur ....
What is the error and how to solve it?
made a mockup https://jsfiddle.net/drno/ahvLcexq/
change the date With

it changes

, the min date in the software should move, but it does not move
