Add update function to install file otherwise additional fields are not not added to db

I had this module enabled.
I updated to the new version
did a drush update
all seemed ok
but the table wasn't actually updated.

PDOException: SQLSTATE[42S22]: Column not found: 1054 Unknown column [error]
'base.created' in 'field list': SELECT base.fid AS fid, base.uid AS uid,
base.filename AS filename, base.uri AS uri, base.filemime AS filemime, base.filesize
AS filesize, base.status AS status, base.timestamp AS timestamp, base.origname AS
origname, base.created AS created, base.published AS published, base.promote AS
promote, base.sticky AS sticky, base.type AS type, base.uuid AS uuid
