Start of my shift (evening); I was asked to travel to ZZZ1 for a Company B717 right aileron change. The previous team working on this aircraft had timed out. Mechanic Y and I (Mechanic X) arrived at ZZZ1 and met up with Inspector Z from ZZZ1 Station at job site. Mechanic Y mentioned he had completed this job before and communicated the previous crew had disassembled as much as they could; but a forklift was required to continue. Mechanic Y and I spent the next couple of hours arranging for a forklift; hangar space and movement of the aircraft. A forklift was procured and Mechanic Y and I started removing the rest of the hardware on the right aileron. [Eventually] the new aileron was on the sling and Mechanic Y and I proceeded to put it on the wing. After the four mounting bolts were installed; I proceeded to work on the outboard end of the aileron and Mechanic Y proceeded to work on the inboard end. [Sometime later] I was finished with the outboard end of the aileron and Mechanic Y was still finishing up the inboard end of the aileron. I then went to work on the other write-up; which was Auxiliary Avionics fan popping circuit breaker. I was in the Forward Cargo Bin changing this fan. [Later] Mechanic Y; Inspector Z and I were ready to hook up [electrical] Ground Power and check out the aileron. We measured the movements as required to confirm the job was completed correctly and all was fine. Some time [later]; Mechanic Y and I cleaned up and prepared to relocate the aircraft back to the gate. The aircraft was at the gate and the paperwork was completed for the acceptance flight. Inspector Z met the crew and performed the steps for the acceptance flight. Mechanic Y and I then waited for the next flight back to ZZZ. Installation incomplete. On-Duty for 13 hours. It is the Inspector's function to ensure jobs are completed properly. A suggestion is that for each job type; the Inspector should have a checklist of the items that he/she is required to ensure have been completed properly; [such as] a Job Card.
I was the (RII) Inspector for a B717 aircraft at ZZZ1 for a Remove and Replacement (R/R) of the right aileron.  All Operational Tests good.  Today; the flight crew at ZZZ2 Station; found aileron tab did not move with aileron. Graveyard shift. Recommend [sending] a Lead Mechanic with the job. On-Duty for 15 hours.
An Aircraft Inspector and Aircraft Maintenance Technician (AMT) are informed the right aileron control tab would not move in the opposite direction of aileron movement on a B717 aircraft after they had signed-off for replacement of the aileron.
