Does anyone know how to enable mikrotik router FTP using Perl script?

Question

my %attrs = ("/ip/service/enable" , "=ftp")
($retval,@results) = Mtik::mtik_cmd(\%attrs);

or

($retval,@results) = Mtik::mtik_cmd('/ip/service/enable ftp' , \%attrs);

Both of these aren't working, im very new at perl so forgive me if its suppose to be simple. Trying to enable FTP in the mikrotik router using my API function in my perl script.
