So while on the Stage touch is working for EaselJS in CocoonJS, it is currently not possible to touch individual EaselJS-DisplayObjects in CocoonJS. I wrote a quick fix for that, in case anyone else needs it.
(updated version to work with EaselJS 0.7+, thx to Jonny)
How to use: Download JS-fix and implement it through a script-tag somewhere after the EaselJS-script-tag and your done!
Hope this helps someone, comment for any issues,cheers!
If you use an older version of EaselJS: easeljs_cocoonjs_touchfix_pre_0.7.js (for pre-EaselJS 0.7)
