Dipladenia plant stopped blooming after 1st blooms came off.

I bought 2 Dipladenia plants from Home Depot and they had quite a few excellent blooms on them. After the initial blooms came off, none have appeared since. I have watered and give them plant food about every 2 weeks. I have not trimmed them back, and vines are climbing and look healthy.

For them to bloom again, do I need to trim them back? I am hoping to eventually attract hummingbirds.
