Cannot show custom dialog on https

[4usmk]

Hi Dev.
Now I have a problem about custom dialog.
When I test my web on https,my custom dialog is not show but it call browser's dialog instead.
When I test it on http,it call my custom dialog normally.
Is it a problem about http/https ? or I miss something.

This is my code

$('#frmCreateInterest').dirtyForms({
message: 'คุณต้องการออกจากหน้านี้โดยไม่ทำการบันทึกข้อมูลใช่หรือไม่ ?',
dialog: {
title: 'แจ้งเตือน',
dialogID: 'custom-dialog',
titleID: 'custom-title',
proceedButtonClass: 'btn-danger',
proceedButtonText: 'ใช่',
stayButtonClass: 'btn-default',
stayButtonText: 'ไม่ใช่'
}
});
Form's Id is #frmCreateInterest .
