Activation of creatures after gaining control of them back with homeward path doesn't work

Today i played with opponent ho took over my cavalier of flame with his card, then after that I activated homeward path to gain control over it back. After that I had 1 colorless and 1 red in my mana pool and I couldn't activate cavalier's ability to give my creatures haste. Normally it works but this time no matter how many times I tried I couldn't activate it. It's probably related to changing controller, but there was nothing unusual said in game log.

Reproduce the reported sequence with Cavalier of Flame, an opponent taking control, and Homeward Path returning control while 1 colorless and 1 red mana are available. Start by tracing control-change handling and the creature’s haste ability activation, then compare the game log with a normal activation. Done means the ability activates after control is returned and the event is represented correctly in the log.
