(Bug)Responsive table extension

xain819

so yea i found i think its a bug (http://editor.datatables.net/examples/simple/responsive.html)
so whenever I un-collapse to show the details i get an [object object] (shown here: http://i144.photobucket.com/albums/r172/izentaishi/1-2.jpg)
but when its normal it goes back and show the data (shown here: http://i144.photobucket.com/albums/r172/izentaishi/2-2.jpg)

my code

                    {data: null, render: function ( data, type, row ) {
                        var convertPeso = '&#8369'+data.totalamountdue.replace('Php', "");
                        return convertPeso;
                    } }
