appended the rowCreatedEvent description in README.

I'm not a native English speaker, so if there're any English syntax errors or the description is too redundant, please improve it.
By the way, do you have a plan about what to implement in your next release, for example, add an optional description of "the x page of y pages" or "Total: xxxx entries"? I intend to add these options because it's also common. I appreciate your code very much because it meets my requirement so well, it's for Bootstrap 3, conjunction with JSON data source and has only basic paging and sorting functions.
Thank you very much.
