If you use dialog id above 32767 it will not work as 32767 is the max dialog id.
This was the problem, there were 3 {'s in the starting but there were only 2 }'s so it took me about 3 seconds to realize there was another } absent, please try and solve your problems by yourself sometimes too.
Good luck.
