iOS Javascript problem

Hi, I have a game which runs fine on android and without any problems , but when I run the same game in iOS there are some problems. I tried to debug and found out that it seems it is completely ignoring any Javascript code and this causes the problem .
In XCode logs it seems the problem is with il2cpp setting. I use Unity 4.6 for this project
I'll appreciate if you can help me with this.
Thanks
