Beginner Gardening: Cane begonia won't bloom, 1 by crayondoom

What I am doing wrong? I don't water it until the first two inches of soil are dry. I mist it a couple times a day. I kept in in an area where it gets indirect light. I moved into my new house a couple months ago, so it has been getting more light (as pictured), but I make sure it doesn't get hot.

The first year we had the plant it started out as a strange stick some lady from craigslist gave us. We kept it in a east facing window at that apartment and it bloomed profusely the second year. At this point we had no idea what this thing was (or why it looked like an angry centipede with scythe legs) and didn't give it any special attention. Then I figured out what it was and the thing decided to stop playing nice. I know begonias aren't always the easiest, but now I feel like I have been challenged by this strange red/green menace (that I love immensely) and I will not stop until I win this little game. Please help me. :)

Side notes: All the stems are less than 3 years old, most are less than 9 months. The plant was severely damaged during a move and the pieces were used to grow new stems. The middle stalk is the newest natural stem (3 months old). It is quite thick compared to the others and has smaller leaves. There is another basal sprout coming up and one of the stems is growing a side shoot.
