medm only updates when a "monitor" is posted by the record for the field
that has changed while a caget retrieves the current value. Most record 
support takes care of posting monitors for you, but for a subroutine
record it is <sometimes> up to you. 

You don't mention which field in the subroutine record is causing the problem,
but it is likely a field in which the record support does NOT do a

     db_post_events(psub,&psub->field,monitor_mask);

If so, you will have to do one in your subroutine code whenever the value
changes. Examples abound in base/src/rec
