Can't make format to work

[freenandes]

At the moment, simple-datatables works well on my project. It has a minor annoyance where, somehow, [data-sort="asc"] doesn't work on page load. I have to go in the default config that I've set up in JS and then define the first column to sort ascending — this way it works.

My biggest problem though is the formatting of dates. As it can be seen on this example: https://jsfiddle.net/c5hpmnvb/2/

It doesn't format it, or maybe I'm doing it wrong because I'm finding it difficult to fill in the blanks in the documentation (due to my noobness level). Can someone give some pointers onto the right direction?

Edit: You can see i added moment.js. I have no clue, after reading the docs, if I need to add it or not for the formatting of dates to work.
