Hi i've made some changes

[kuzemchik]

Allmost about options.
Time disappearing fixed, min max is working now (i've checked twice =) ).
onSelect subscribe is now working for options (i mean slider time changes).

I've added in your changes for onSelect, they work beautifully. However I tried this example (from the documentation)

$('#example14').datetimepicker({

    //minDate: new Date(2010, 11, 20, 8, 30),

    maxDate: new Date(2010, 11, 31, 17, 30)

}).datetimepicker('option','minDate',new Date(2010, 11, 20, 8, 30));

and maxDate works as expected, but with minDate only the date is restricted, the time can go below 08:30. I'll go ahead and close this pull since I've added your changes to dev and I'll be merging some other changes as well. (Be sure to fork from the dev branch and issue your pull from that branch as well if you make any further changes). Thanks for all your work!

I'll try to figure out what's with this example on tomorrow.

Currently such code works.

$('#example14').datetimepicker({

    //minDate: new Date(2010, 11, 20, 8, 30),

    maxDate: new Date(2010, 11, 31, 17, 30)

}).datetimepicker('option','minDateTime',new Date(2010, 11, 20, 8, 30));

I have some time, so I'll try to find out better solution.
