What happens if you compile with minify ?
I ask because according to Ashley the minify/obfuscate option on compile uses Google's Closure Compiler in advanced mode.
and according to Google info, the advanced mode goes through looking for simple functions and "inlines" them.
So if the functions as used in events appear as functions in the JS output then maybe these types of simple functions will not even be functions in compiled code.
"....Compilation with ADVANCED_OPTIMIZATIONS replaces the call to displayNoteTitle() with the single alert() that composes the function's body. This replacement of a function call with the function's body is known as "inlining". If the function were longer or more complicated, inlining it might change the behavior of the code, but the Closure Compiler determines that in this case inlining is safe and saves space. Compilation with ADVANCED_OPTIMIZATIONS also inlines constants and some variables when it determines that it can do so safely...."
