V2 Column ordering with edited data

First of all, apologies if this is not the correct place to report bugs for V2 of Datatables, second apologies again if this is not a bug and simply a misunderstanding of implementation.

Unfortuantly I am unable to link to a live version so I have replicated it using the test suite.

As you can see I have modified cell value inside the rowCallback function, doing this does not get taken into account when then ordering that particular column...

I saw in the documentation that you can set orthagonal data using data-sort but again this does not seem to have any effect when doing so (also demonstrated) in the rowCallback function.

In my implementation I am unable to set the order at markup level as I use ajaxsource with an aaData object to return the values to be added to the table.

If I am indeed correct that this is a bug, I am not sure how difficult it would be but perhaps an implementation idea could be to supply two values inside the aaData object

eg...

{"aaData":[
    [
        28,
        "00011",
        "PY/66732",
        "Someones Name",
        {
            display : "ABCD",
            order : "SomeValueThatShouldDisplaySecondWhenOrderedAlphabetically"
        }
    ],
    [
        65,
        "00012",
        "PY/54356",
        "Protected For Integrity",
        {
            display : "EFGH",
            order : "AnotherValueTheShouldDisplayFirstWhenOrderedAlphabetically"
        }
    ]
]}

Hopefully this is easy enough to understand, I am relatively new to reporting problems (if as alluded to previously this is a problem at all)
