Title: Add scope to success and error callbacks

"The this reference within all callbacks is the object in the context option passed to $.ajax in the settings; if context is not specified, this is a reference to the Ajax settings themselves."

Currently the scope for `success` and `error` use the Window object. This PR passes the correct context of the callback through.
