Get the Sum of checked checkbox for each row of table

I want to get the sum total of check box for each row in a table

Javascript : For Sum

        $('input[type="checkbox"]').change(function() 
      {
            var total = 0;
        $('#mytable tr').each(function()
      {
            total += parseInt($(this).val());    
        $(this).parents('tr').find('input[type=text]:last').val(total);
      }); 
     });

Javascript : For Count

        $('input[type="checkbox"]').change(function() {
        $('#mytable tr').each(function() {
           var count = $(this).find(':checkbox:checked').length;
         $(this).find('#count').val(count);
       });
       });

In the First image when i click Select All ,it shows 1 in paper count and 10 in sum column. Then,when i click Select All for second time paper count increase in correct way but no change in sum column.I want to know,How to write for each function . I want to sum the checked checkbox value when selected indiviually and when select by Select All Option
