Mac iCal is not syncing through iCloud to iPhone iCal (after password change)

After I had to change my Apple ID password, the iCal of my iPhone 4S and Macbook Pro are not syncing. iCloud is turned on on both, and when I refresh they seem to be refreshing as normal but do not sync.

I turned iCloud on and off on my iPhone, but it still does the same. Please help!

Thanks in advance.
