How to reload table on each button click

laputatc

Hi All
I have successful to run datatable at one time as below code

$(document).ready(function () {
        $("#TableCurrentList").hide();
        $('#datetimepicker1').datetimepicker();
        $('#datetimepicker2').datetimepicker();
        $('#cmdList').on('click', function () {
            $("#TableCurrentList").hide();
           // $("#TableCurrentList").DataTable().clear().draw();

            var url = '@Url.Action("GetElecticList1", "Home")';
            $("#TableCurrentList").show();
            
            $("#TableCurrentList").DataTable({
                
                "processing": true, // for show progress bar
                "serverSide": true, // for process server side
                "filter": true, // this is for disable filter (search box)
                "orderMulti": false, // for disable multiple column at once
                "pageLength":13,

                "ajax": {
                    "url": url,
                    "type": "POST",
                    "datatype": "json",
                    "data": {"datefr" : $("#txtDateFr").val(), "dateto" :$("#txtDateTo").val() }
                },
                "columnDefs":
                    [{
                        "targets": [0],
                        "visible": false,
                        "searchable": false
                    },
                        {
                            targets: 1,
                            render: function (data) { return moment(data).format('YYYY/MM/DD HH:mm:ss'); }
                        }
                        
                    ],

                "columns": [
                    { "data": "id", "name": "id", "autoWidth": true },
                    { "data": "dtRecDateTime", "name": "dtRecDateTime", "autoWidth": true },
                    { "data": "fCurrentW", "name": "fCurrentW", "autoWidth": true },
                ]
            });
        });

    });

But when I click again, I get initialize error. it seem need to add table reload on every click. Can I know to do it ?
Thank you
