Jayiya, who hit the fastest hat-trick in PSL history on Monday, is contracted to the Citizens until June.
The 26-year-old has netted five goals and provided one assist in nine league starts and seven substitute outings in 2016/17.
"We are talking. We want to keep him next season," Comitis tells snl24.com/kickoff.
Meanwhile, Comitis says new Malawian signing Isaac Kaliati will only start playing for the club next term.
"His contract with his club expired after the 31st of January and we could not register him. We have allowed him to go home to sort his papers and he should be back soon to be part of the programme and prepare for next season."
