Whats wrong with searchPath?

Hi i am doing an app update by using AsstesManager…
the app already downloads all the resources from the server then i restart the game…
i set the search path like this

if(cc.sys)
 {
    var path = cc.sys.localStorage.getItem("path");
    if (path)
    {
        // path is "[/data/data/org.cocos2dx.mygame/files/]"
        path = path.substring(1,path.length - 1);
        jsb.fileUtils.setSearchPaths(path.split(','));
    }
}

cc.game.onStart = function()
{
.....
}
