hi! Have you found any solution?

Not sure if it is the issue, but it strikes me as odd. For the Widget class it uses the function init, not initialize. You should also be calling super whenever extending a function on a class you are extending. Adding the following in the new init function should help:

this._super.apply(this, arguments);

Also, whenever debugging JavaScript use 'Developer mode with Assets' as it really helps pinpoint in which JS file the error occurred.
