That's not really how you're supposed to use internals and this variables.

Consider using the prototype chain instead.

#self:

Using self the way you did is literally pointless. I don't know whether you're a Python dev and that feels familiar, but that's wrong.

#jQuery:

You use jQuery for document.ready, $(selector) and .append, I would recommend removing it. Using a library of jQuery's size for those three functions is just pointless when you can use polyfills from vanilla JavaScript.
