I was given one of these a couple of years ago and it has now become 5 and all have flowered in the last few weeks.
When you repot, make sure its shoulders are above the compost and give it a good feed of liquid rose or tomato food. As with any bulb, keep it fed and wtered till the leaves die down then let it rest, although I find my lot always have some greenery to keep going. I keep the pots out of the way on a bright but north facing window sill.
Either way, start feeding and watering again in autumn to encourage the next set of flowers. My two biggest now produce two flower stalks. Offsets from the bulb can take a couple of years to grow to flowering size.
