Jquery Keyup in Column

Question

I created a table, sum columns and rows. The problem I have is:

When I click the "+" button, I can sum the rows but I have a Problem with the columns. I think it's a problem with KeyUp, but I don't know.

This is the code that sum Columns:

$('#sum_table tr:not(.totalCol) input:text').bind('keyup change', function() {
    var $table = $(this).closest('table');
    var total = 0;
    var thisNumber = $(this).attr('class').match(/(\d+)/)[1];

    $table.find('tr:not(.totalCol) .sum'+thisNumber).each(function() {
        total += parseInt(this.value);
    });

    $table.find('.totalCol td:nth-child('+thisNumber+')').html(total);
});

Code that increment rows and columns:

$("#tabla").click(function () {
        $("tr").find("td:last").before('<td><input type="text" value="0"></td>');
        var linea = $('tr:first').html();
        $('tr:last').before('<tr>'+linea+'</tr>');
        $('tr').last().find("td").last.html('<td>hola</td>');
    });

I've changed the + button click in your fiddle

$("#tabla").click(function () {
   $("#sum_table tr:last-child").before('<tr><td><input type="text" value="0"></td><td><input type="text" value="0"></td><td><input type="text" value="0"></td><td class="total"> 0 </td></tr >');

});

Demo

Edit You need to use on delegate for newly created textbox keyup event,

$(document).on('keyup change', '#sum_table tr:not(.totalCol) input:text', function () {
       var $table = $(this).closest('table');
       var total = 0;
       var thisNumber = $(this).attr('class').match(/(\d+)/)[1];

       $table.find('tr:not(.totalCol) .sum' + thisNumber).each(function () {
           total += parseInt(this.value);
       });

       $table.find('.totalCol td:nth-child(' + thisNumber + ')').html(total);
   });

Updated fiddle

Edit

$("#tabla").click(function () {

    $("#sum_table tr:last-child").before("<tr>" + $("#sum_table tr:eq(0)").html() + "</tr>");
    $("tr:not(:last-child)").each(function () {
        var classname = $(this).find("td:last-child").index() + 1;
        $(this).find("td:last-child").before('<td><input class="sum' + classname + '" type="text" value="0"></td>');
    });
    $("#sum_table tr:last-child").append("<td>0</td>");


});
