多种形式的Ajax响应不起作用

Question

I have a problem with working on multiple forms from an AJAX response that didn't working for me.

Here is the main AJAX:

$(document).ready(function() {
            $('#routine').click(function(){
    var ids = $.map($('#table').bootstrapTable('getSelections'), function (row) {
    return row.StaffId
    });
    id=ids[0];
    if(!ids[0])
          msg("Please Select a Staff");
    else{
        $("#loginScreen").show();
        msg('Please Wait...');
        $.ajax({url: "staff.php?action=getroutine&SID="+id,
        type:'GET',
        success: function(s){
        msgclose();
        $("#contd").html(s);
        },
        error: function(e){
        msg('Error Processing your Request!!');
        }
     });
    }           
  });
});

And the staff.php file is as follows:

for($d=0;$d<6;$d++)
        {
        echo"<tr>
                <form class='form-horizontal' role='form' id='d".($d+1)."' onsubmit='javascript: return false;'>
                <td>".$days[$d]."</td><input type='hidden' id='day".($d+1)."' value='".$days[$d]."'>
                <td>
                    <select class='form-control' id='".$days[$d]."class1' name='class1' onchange='getComb(this)'>

                </td>                   
            <td>
            <button type='submit' class='btn btn-success'>Save Change</button>
            </td>
            </form></tr>";
        }
        echo"</tbody>
    </table>
</div>";

Now I have 6 form IDs d1 to d6 and in the main page I have the following functions for each form:

$(document).on('submit','#d1',function(){
    var formData = $('#d1').serializeObject();
    msg("FormData="+formData);
});
$(document).on('submit','#d2',function(){
    var formData = $('#d2').serializeObject();
    msg("FormData="+formData);
});
$(document).on('submit','#d3',function(){
    var formData = $('#d3').serializeObject();
    msg("FormData="+formData);
});

$(document).on('submit','#d4',function(){
    var formData = $('#d4').serializeObject();
    msg("FormData="+formData);
});
$(document).on('submit','#d5',function(){
    var formData = $('#d5').serializeObject();
    msg("FormData="+formData);
});
$(document).on('submit','#d6',function(){
    var formData = $('#d6').serializeObject();
    msg("FormData="+formData);
});

The SUBMIT button for each form is supposed to be showing a message with form data but they are not working. Help me please.
