Thanks for contacting Syncfusion support.
We have analyzed your query and we are not able to reproduce the reported issue. We have checked based on your code example provided and shown the dateTimepicker in the custom template dialog and when saving it saves the data properly while using remoteSaveAdaptor in grid
We have also prepared a sample that can be downloaded from the below link.
