Ive got some Problems with the Datetimepicker, everytime i select a date .. it delays with like 1 second and i get error messages in visual studio (watch here: )

Thats my code: `
var input = $(" " ) input.appendTo($(element));

//DATETIMEPICKER ALLGEMEIN
input.datetimepicker({
    monthNames: ['Januar', 'Februar', 'März', 'April', 'Mai', 'Juni', 'Juli', 'August', 'September', 'Oktober', 'November', 'Dezember'],
    monthNamesShort: ['Januar', 'Februar', 'März', 'April', 'Mai', 'Juni', 'Juli', 'August', 'Septem.', 'Oktober', 'Novem.', 'Dezem.'],
    dayNames: ['Sonntag', 'Montag', 'Dienstag', 'Mittwoch', 'Donnerstag', 'Freitag', 'Samstag'],
    dayNamesMin: ['So', 'Mo', 'Di', 'Mi', 'Do', 'Fr', 'Sa'],
    dateFormat: 'dd.mm.yy',
    changeMonth: false,
    changeYear: true,
    yearRange: '2015:2019',
    showButtonPanel: true,
    timeText: 'Zeit',
    hourText: 'Stunde',
    minuteText: 'Minute',
    secondText: 'Sekunde',
    ampm: false,
    controlType: 'select',
