Human Factors
Two helicopters at least one was a Law Enforcement Department were in a pattern for RW XX at ZZZ. We were cleared for the ILS XY and were on final below 1;000 feet AGL (?). We got an RA with a climb warning from one of the helos that was climbing into us. I disconnected the auto pilot and started a climb. The VSI showed a climb requirement of over 4000 FPM. Somehow the helicopter avoided us and by the time I stopped the climb we were no longer in a stabilized approach. We elected to go around. After we went white needles/Nav mode I noticed that we were not turning for the published missed approach. I disconnected the A/P and started the turn. At the same time ATC told us to turn to heading 210. Afterwards we realized that because I did not hit the TOGA button the A/P did not capture the missed approach. I think we missed the helicopter by less than 300 feet. the second approach was without issues.
CRJ-900 Captain reported a NMAC with a helicopter during approach and while flying the missed approach a track deviation occurred.
