Datetime Combo doesn't show in quickcreate sub panel


May be someone can point me in the right direction about this error:

I use two datetime fields in a custom module, when I edit a record the datetime field is showed fine, but if I try to edit the same record as a subpanel (with the quickcreate layout), the datetime only show the date part, the calendar picker doesn’t work and the time part is missing.

When I inspect the error in the browser console, this field gave me this message

ReferenceError: Can’t find variable: combo_FIELDNAME.

Thanks in advance for the help with this.
