My autumn raspberries always fruit in August - getting a lovely crop now, some for breakfast some for supper and lots in the freezer and more to pick this morning - but they're planted in the ground against a fence and as they grow I loop plastic covered wire around them to hold them against the fence so they don't get blown about.
Raspberries grow tall and in pots they're likely to be top-heavy. Have you got them in heavy loam-based compost? And they do need something to tie them up to - I'd put the pot against a fence or post and put some gardener's twine around them to hold them up.
