CCEditBox not working in OSX

Hi, I am trying to use CCEditBox with Mac OSX but it doesn’t allows me to write anything. I know it is calling convertDesignCoordToScreenCoord, setContentSize and setAnchorPoint because of the outputs at debugging but not sure what else is calling. I’ve tried running the ExtensionTest->EditBoxTest for cpp, lua, and javascript and is not working. I am currently testing it using cocos2dx V3.0 alpha0. Is this expected behaviour, known bug or what? Does it works in alpha1? Thanks in advance. (I am tying to implement it using JSB by the way).
