This should work:

<script type="text/javascript">
$(document).ready(function () {
   $('#updates').click(function (e) {
       e.preventDefault();
        var data = {};
        data.region_text = $('#t_region').val();
        data.town_text = $('#t_town').val();
        data.uniq_id_text = $('#t_uniq_id').val();
        data.position_text = $('#t_position').val();
        data.salary_grade_text = $('#t_salary_grade').val();
        data.salary_text = $('#t_salary').val();

        for(var $x=1;$x<=15;$x++) {
            data['id'+$x+'_text'] = $('#id'+$x).val();
            data['aic'+$x+'_text'] = $('#aic'+$x).val();
            data['name'+$x+'_text'] = $('#name'+$x).val();
            data['optA'+$x+'_text'] = $('#optA'+$x).val();
            data['optB'+$x+'_text'] = $('#optB'+$x).val();
            data['optC'+$x+'_text'] = $('#optC'+$x).val();
            data['optD'+$x+'_text'] = $('#optD'+$x).val();
            data['other_qual'+$x+'_text'] = $('#other_qual'+$x).val();
            data['interview'+$x+'_text'] = $('#interview'+$x).val();
            data['total'+$x+'_text'] = $('#total'+$x).val();
        }

        $.ajax({
            type: "POST",
            url: "update.php",
            data: data,
            cache: false,
            success: function (response) {
            // We are using response to distinguish our outer data variable here from the response
            }
        });
    });
});
</script>
