Change JSON value with Javascript or JQuery

Question

I have the following code. However, the problem with it is that it does not change nameElem.data('index'), so whenever the code runs it only shows element 1 in the list. How can I change the nameElem.data('index') json value? I tried cardInfo[i].data.index = index;, but that did not work.

$('#next').on('click', function(e) {
    e.preventDefault();
    var nameElem = $('#team-name');
    var entries = nameElem.data('entries');
    var index = (nameElem.data('index') + 1) % entries.length;
    nameElem.text(entries[index]);
})

Keeping it simple: How do I set a json value - nameElem.data('index') to var index?

It's not a JSON value, I don't know why you're talking about JSON values... But anyways:

nameElem.data("index",index);

That should do it.

That did it - what is it then, if it's not a JSON value - sorry I thought it was one - today was actually my first time dealing with JSONification so I just assumed this was it. Anyways - what type of value is it, @Kolink ?

It's a data attribute. JSON is a string that represents an object, such as "{foo:'bar'}"
