Datatables for going a bit crazy

Fran25ans

I want to join the two codes but it does not work, you can help me?

$(document).ready(function() {
    $('#tabla').DataTable( {
        "language": {
            "lengthMenu":"Mostrar _MENU_ registros por página.",
            "search" : "Buscar",
             "zeroRecords": "Lo sentimos. No se encontraron registros.",
            "info": "Mostrando página _PAGE_ de _PAGES_",
            "infoEmpty": "No hay registros aún.",
            "infoFiltered": "(filtrados de un total de _MAX_ registros)",
            "LoadingRecords": "Cargando ...",
            "Processing": "Procesando...",
             "SearchPlaceholder": "Comience a teclear...",
             "paginate": {
     "previous": "Anterior",
     "next": "Siguiente", 
      }
        },
     
  
   "sort": false
  
} );
} );

AND

$(function () {
    if ($('.dataTable').length > 0) {
        $('.dataTable').dataTable({
            "bPaginate": true,
                "bLengthChange": false,
                "bFilter": true,
                "bSort": true,
                "bInfo": true,
                "bAutoWidth": false,
                'aoColumnDefs': [{
                'bSortable': false,
                    'aTargets': ['nosorting']
            }],
            
 
 });
 $(document).on('keyup', "input[type='number']", function(){
var oTable = $('.dataTable').dataTable();
 oTable.fnFilter($(this).val());
});
        $('.dataTables_filter').empty(); // clears the content generated    
        $('.dataTables_filter').append("<div class='input-group' style='width: 250px'>" +
            "    <input type='number' class='form-control' placeholder='Search..'/>" +
            "    <span class='input-group-addon'>" +
            "        <i class='fa fa-search' style='width: 15px; padding-left: 5px'></i>" +
            "    </span>" +
            "</div>")
    }
});
