Works correctly in my test case - thank you!

According to https://api.jquery.com/data/#data-html5 you can use $this.attr( 'data-i18n' ) to retrieve the value directly as a string. However, its behavior may differ in a few cases (e.g. message keys resembling arrays, programmatic use of .data()).

@ricordisamoa Should I make the changes or is my previous commit fine?

@deepikap1 dd1beba looks unrelated commit here.
