Do Conquistadors actually work?

[Idleray]

I'm playing as Spain with my own founded religion dominant in all my cities, attacking and capturing a city with
2 Adjacent Conquistadors, one adjacent to city and one attacking for final blow on city.

The city has a different religion, so after capturing it I expected that the ability of Conquistadors would work and change its religion from Taoism to my own (catholicism). Didn't happen. Do they actually work?

I didn't manage to capture a city with my spain game, but maybe you need to be in an escort formation with a missionary to do it? That's all I can think of right now.

as it happens that was also the case, though the civilopedia says nothing about needing a missionary.

Ok so this is what actually happened:

I attack and capture a city with 4 Catholics (my religion) and 3 Taoists with a Conquistador w/ apostle in same hex. The result is a city with still 3 Taoists but only 2 Catholics.

Funny thing is when I hold off capturing this city and retry next turn, I get 3 Catholics and 2 Taoists, but I get this result regardless of whether there is are Conquistadors involved or not (I moved them away and used a knight)
