CodeIgniter, shows the first 10 elements, the rest do not come out, the last one is shown, using modal

I have a modal list and it only shows me the top 10 well, when I go to the next window it shows me anything of the last thing I touch but it does not show the real value that it can be. my list has 25 elements

vista lista.php

<div class="btn-group">
<button type="button" class="btn btn-info btn-view-asistencias" data-toggle="modal" data-target="#modal-default" value="<?php echo $modulod->id;?>">
<span class="fa fa-search"></span>
</button>
</div>

Vista footer.php

$(".btn-view-asistencias").on("click", function(){
        var id = $(this).val();
        $.ajax({
            url: base_url + "registro/asistencias/view",
            type:"POST",
            data:{idasistencias:id},
            success:function(resp){
                $("#modal-default .modal-body").html(resp);
            }

        });
    }); 

which can be the error
