Hello friends, I have a problem with datatables and datepicker

in a table show the results of my database and show a calendar when I choose a calendar date results should be filtering, the problem is when I select a calendar date no longer filters the results

the code that I have is this

$.datepicker.regional['es'] = {
    closeText: 'Cerrar',
    prevText: '<Ant',
    nextText: 'Sig>',
    currentText: 'Hoy',
    monthNames: ['Enero', 'Febrero', 'Marzo', 'Abril', 'Mayo', 'Junio', 'Julio', 'Agosto', 'Septiembre', 'Octubre', 'Noviembre', 'Diciembre'],
    monthNamesShort: ['Ene','Feb','Mar','Abr', 'May','Jun','Jul','Ago','Sep', 'Oct','Nov','Dic'],
    dayNames: ['Domingo', 'Lunes', 'Martes', 'Miércoles', 'Jueves', 'Viernes', 'Sábado'],
    dayNamesShort: ['Dom','Lun','Mar','Mié','Juv','Vie','Sáb'],
    dayNamesMin: ['Do','Lu','Ma','Mi','Ju','Vi','Sá'],
    weekHeader: 'Sm',
    dateFormat: 'yy-mm-dd',
    firstDay: 1,
    isRTL: false,
    showMonthAfterYear: false,
    yearSuffix: ''
} ;

$.datepicker.setDefaults($.datepicker.regional['es']);

var oTable = $('#example').dataTable( {
    "sPaginationType": "full_numbers",
    "bProcessing": true,
    "bServerSide": true,
    "sAjaxSource": "server_processing.php",
    "fnServerParams": function (aoData, fnCallback) {
        /*aoData.push(  {"name": "datepicker_min", "value":  $('#datepicker_min').val() } );
        aoData.push(  {"name": "datepicker_max", "value":  $('#datepicker_max').val() } );*/
        aoData.push(  {"name": "datepicker_min2", "value":  $('#datepickercalendario').val() } );
        aoData.push(  {"name": "datepicker_max2", "value":  $('#datepickercalendario').val() } );
    },

    "aaSorting": [[ 0, "desc" ]],

    "oLanguage": {
        "sLengthMenu": "Mostrando _MENU_ eventos por página",
        "sZeroRecords": "No se encontro Nada - Disculpe",
        "sInfo": "Mostrando _START_ de _END_ de un total de _TOTAL_ eventos",
        "sInfoEmpty": "Mostrando 0 de 0 de un total de 0 eventos",
        "sInfoFiltered": "(filtrados de _MAX_ total de eventos)",
        "sSearch": "Buscar",
        "oPaginate": {
            "sFirst": "Primera",
            "sLast": "Última",
            "sNext": "Siguiente",
            "sPrevious": "Anterior"
        }
    }
});

$( "#datepickercalendario" ).datepicker ( {
    dateFormat: 'yy-mm-dd',
    numberOfMonths: 1,
    "onSelect": function(date) {
        min = new Date(date).getTime();
        max = new Date(date).getTime();
        oTable.fnDraw();
    }
})

.keyup( function () {
    DateFilter = new Date(this.value).getTime();
    DateFilter = new Date(this.value).getTime();
    oTable.fnDraw();
});

$( "#datepicker_min" ).datepicker( {

} );

$( "#datepicker_max" ).datepicker( {

} );
