You are not loading your library, so glade does not know the properties
 DlgUtils_DatumEingabe has.

since you specified parent="GtkEventBox", glade will use that as the
base of DlgUtils_DatumEingabe but you need to specify the param spec of
each property you want to edit in glade (see https://developer.gnome.or
g/gladeui/3.20/properties.html)

I recommend trying to load your library 
<glade-catalog name="foo" library="foo" depends="gtk+">
