[Moo] this.myMethod() and this.setOptions() are not working!

[Douglas Machado]

Greetings,

I'm having a hard time to make a method to work correctly and I appreciate 
if anyone could help me out;

I have uploaded the script to this JSFiddle:
http://jsfiddle.net/machadoug/LPVkv/1/

It is not executing this method below
this.hideAll(i);

Also, if I uncomment this.setOptions() I get this error in Firebug's 
console:

TypeError: this.setOptions is not a function


Thanks in advanced for your help,
