Loading JSON from local dynatable

I'm trying to do something very similar to the last comment of this question - that is to load a whole bunch of data in an ajax call but then put it into dynatable as though it's a local JSON file. I am none to proficient at javascript/jquery, so it's probably something fairly obvious, but I can't get it to work. My current code looks like this:

<table id="my-ajax-table">
  <thead>
    <th>Some Attribute</th>
    <th>Some Other Attribute</th>
  </thead>
  <tbody>
  </tbody>
</table>

<script>

$.getJSON('/dynatable-ajax.json', function(data) {
      $('#my-ajax-table').dynatable({
      dataset: {
        records: data
      });
    });

and the ajax url returns this:

[
{"someOtherAttribute": "Fetched by AJAX", "someAttribute": "I am record one"},
{"someOtherAttribute": "Cuz it's awesome", "someAttribute": "I am record two"},
{"someOtherAttribute": "Yup, still AJAX", "someAttribute": "I am record three"}
]

Which is right out of the tutorial.

I'm assuming it's my $.getJSON that's wrong. Should I be using a success and failure case? What would that look like? Should I be using parseJSON?

Thanks a lot, Alex

In the end I changed the javascript to this and it worked:

<script>
$.getJSON('/dynatable-ajax.json', function (response) {     
  $('#my-table').dynatable({
  dataset: {
    records: response
  },
});

});
</script>

Not entirely sure what was wrong with the first version, I think there are too many bracket closes or something.
