Narrative:

Event started on short final in the landing phase. Roughly 1;000 feet. Flight attendant called up emergency light/chimes. Stated visible smoke/fumes mid cabin. I was pilot flying; (no EICAS messages observed) first officer asked if the smoke was building and if they'd recommend an evacuation. Both fas answered yes. We [advised] tower and landed. We exited the runway and ran the evacuation checklist. Passengers were deplaned using the main cabin door stairs. Passengers were bussed back to the terminal; no reported injuries.after the fire department/ops/ground crews were done they allowed us back on to get our gear and gather our belongings. They wanted us to ride in the airplane back to the gate so that we could release the brake so they could tow the airplane in. Climbing back into the airplane I saw the emergency lights were still on. I turned those off and saw the fire bottle lights on the glare shield were illuminated. I believe; in my haste to reset the aircraft/remove lights; I must have pushed the discharge buttons instead of releasing the fire-push switch lights. Maintenance had notified me the bottles were discharged.
