                var newDiv = $('.ai_service').find('div:first').clone();

                newDiv.find('input').each(function () { $(this).val(''); });
                $('div.ai_service:first div:last').before(newDiv);
            });

            $('a.remove_input').live('click', function (event) {
                event.preventDefault();
                $(this).closest('div').remove();
            });
        });

Assign a empty value to the cloned input:

var input = $column.clone().val('').wrap("<div />").parent().html();

Instead of cloning and appending, you can insert and remove nodes before or after siblings:

 $('a.add_input').click(function() {
        $('a.remove_input').before('<input type="text" name="service[]" style="width: 155px;" placeholder="خدمات دیگر" title="خدمات دیگر" />');
    });

A simplified version of your code can then be written thus.
