nomi1122

My initialization is

            var editor;
            editor = new $.fn.dataTable.Editor( {
            ajax: "includes/processes/datatables.php?actionDD=IndbMark",
            table: "#IndbMark",
            fields: [
                {
                    label: "ID:",
                    name: "ss_benchmarksector.ID",type:"hidden"
                },{
                    label: "Benchmark:",
                    name: "ss_benchmarksector.BenchmarkID", 
                    type:'select'
                }, 
                {
                    label: "Sector:",
                    name: "ss_benchmarksector.SectorID",
                    type:"select"
                },
                {
                    label: "Value:",
                    name: "ss_benchmarksector.Value",
                },
                {
                    label: "Notes:",
                    name: "ss_benchmarksector.Notes",
                }
            ]
            } );
                // Activate an inline edit on click of a table cell
                $('#IndbMark').on( 'click', 'tbody td:not(:first-child)', function (e) {
                    editor.inline( this, {
                        buttons: { label: '>', fn: function () { this.submit(); } }
                    } );
                } );

                $('#IndbMark').DataTable( {
                    dom: "Bfrtip",
                    ajax: "includes/processes/datatables.php?actionDD=IndbMark",
                    responsive: true,
                    destroy: true,
                    columns: [
                        {
                            data: null,
                            defaultContent: '',
                            className: 'select-checkbox',
                            orderable: false
                        },

                        { data: "ss_benchmarksector.ID" },
                        { data: "ss_benchmark.Name",editField:"ss_benchmarksector.BenchmarkID"},
                        { data: "sel_sector.NAME",editField:"ss_benchmarksector.SectorID"},
                        { data: "ss_benchmarksector.Value"},
                        { data: "ss_benchmarksector.Notes" },
                    ],

                    order: [ 1, 'asc' ],
                    select: {
                        style:    'os',
                        selector: 'td:first-child'
                    },language: {
                        searchPlaceholder: "Search records",
                        search:""
                    },
                    buttons: [
                        { extend: "create", editor: editor },
                        { extend: "edit",   editor: editor },
                        { extend: "remove", editor: editor }
                    ]
                } );

The remove button is removing the row from the table but it couldn't delete from database. It down't give any error.
