formatting a pre block to remove the first indent after Ajax has inserted data into a html code block?

I usually use the below snippet to remove the first indent from my < pre >< code > blocks which works fine.

However im using an Ajax call to populate the html of the code block, which when completes it doesnt format anymore, ive tried to put the pre formatting code after the result is populated too but it still comes out with the large indent on the first line

I also tried to format the data.result with, which didn't work either

var pattern = data.result.match(/\s*\n[\t\s]*/);
results.html(data.result.replace(new RegExp(pattern, "g"),'\n'));

here is the code:

<script>
    $("pre").each(function(){
        var html = $(this).html();
        var pattern = html.match(/\s*\n[\t\s]*/);
        $(this).html(html.replace(new RegExp(pattern, "g"),'\n'));
    });
    var waiting = $('#waiting').hide()
    {% if task_id %}
        var task_id = "{{ task_id }}";
        var results = $('#results');

        get_task_info(task_id);

        function get_task_info(task_id) {
            $.ajax({
                type: 'get',
                url: '/monitoring/get_task_info/'+task_id,
                data: {'task_id': task_id},
                success: function (data) {
                    results.html('');
                    if (data.state == 'PENDING') {
                        waiting.show();
                    }
                    else if(data.state == 'SUCCESS'){
                        waiting.hide();
                        results.html(data.result);
                        $("pre").each(function(){
                            var html = $(this).html();
                            var pattern = html.match(/\s*\n[\t\s]*/);
                            $(this).html(html.replace(new RegExp(pattern, "g"),'\n'));
                        });
                    }
                    if (data.state != 'SUCCESS') {
                        setTimeout(function () {
                            get_task_info(task_id)
                        }, 2000);
                    }
                },
                error: function (data) {
                    results.html("Error!");
                }
            });
        }
    {% endif %}
</script>

oddly enough, in the fiddle neither option works, I have the large indent where there is supposed to be none...
