jquery - Datatables columnFilter plugin: not working with multiple date-ranges -

filtering works fine until add 2 or more date-range filters - e. g. 1 date-range column filter works fine.

when add 2 or more date-range column filters, filters cease work (typing of filters shows 0 output).

what problem?

        var otable = $('#sample_editable_1').datatable({             "alengthmenu": [                 [5, 15, 20, -1],                 [5, 15, 20, "all"] // change per page values here             ],             // set initial value             "idisplaylength": 5,             "sdom": "<'row-fluid'<'span6'l><'span6'f>r>t<'row-fluid'<'span6'i><'span6'p>>",             "spaginationtype": "bootstrap",             "olanguage": {                 "slengthmenu": "_menu_ records per page",                 "opaginate": {                     "sprevious": "prev",                     "snext": "next"                 }             },             "fndrawcallback": function( osettings ) {                 //callback fndraw, otherwise overflowed table                 //because datatables seem update width of table                 //to fixed value after redraw                 $("#sample_editable_1").css('width', '100%');             }             /*"aocolumndefs": [{                     'bsortable': false,                     'atargets': [0]                 }             ]*/         }).columnfilter(            {                  aocolumns: [                                 {                                      type: "date-range"                                 },                                 {                                      type: "text",                                      bsmart: true                                 },                                 {                                      type: "select",                                      values: entities                                 },                                 {                                      type: "text"                                 },                                 {                                      type: "number"                                 },                                 {                                      type: "text"                                 },                                 {                                      type: "select",                                      values: payment_form                                 },                                 {                                      type: "date-range"                                 },                                 {                                      type: "text"                                 },                                 {                                      type: "select",                                      values: check_status                                 },                                 {                                      type: "text"                                 },                                 {                                      type: "text"                                 },                                 {                                      type: "text"                                 },                              ]            }         );
