Placing columns inside bootstrap modal

Question

I'm trying to get a Bootstrap model to have multiple columns inside it, however it does not appear to be working with my content appear vertically as opposed to in columns. My code is here:

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog modal-lg">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
                <h4 class="modal-title" id="myModalLabel">Modal</h4>
            </div>
            <div class="modal-body">
                <div class="row">
                    <div class="row-md-6">
                        Left
                    </div>
                    <div class="row-md-6">
                        Right
                    </div>
                </div>

            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                <button type="button" class="btn btn-primary">Save changes</button>
            </div>
        </div>
    </div>
</div>

I've found a few things around that solved this issue with Bootstrap 2, but they don't work with Bootstrap 3. I've also tried changing the row-md-6 to sm, xs etc, but no luck. Is it possible to do it in Bootstrap 3? Columns would be the most ideal thing for me, but should I avoid columns all together?

There is no row-md-* in Bootstrap, but col-md-* should work..

    <div class="modal-body">
          <div class="row">
            <div class="col-md-6">
              Left
            </div>
            <div class="col-md-6">
              Right
            </div>
          </div>
    </div>
