I went some websites like forums and facebook pages, there are developers were discussing about CocoonJS isn't an option to export iOS and Android by HMTL5 game, they basically tell CocoonJS is a broken tool due to lack of sound support and dynamic memory support.
Ludei tells us do not use a lot of images and sound files, it shouldn't be any problem.
Overall, you cannot make robust games with CocoonJS.
