jquery - createdCell not getting created when .draw() is called after data edit -


i'm using datatables jquery plugin. table renders want when datatable created on page load.

the problem - when update data row (after editing). createdcell have defined in column 2 not getting created upon redrawing table

var sitetable = $('#datagrid').datatable({ ...removed settings not seem relevant problem... columns: [         {             data: null,             defaultcontent: '',             classname: 'select-checkbox',             orderable: false         },         {             data: null,             defaultcontent: '',             orderable: false,             sortable: false,             createdcell: function (td, celldata, rowdata, row, col) {                 $(td).append(                     $("<button class='btn-edit-row'><i class='glyphicon glyphicon-pencil'></i></button>")                 );             }          },                   { data: "site", title: "site", class: "align-center", sortable: true, orderable: true },         { data: "offsetx", title: "offset-x", class: "align-right", sortable: false, orderable: true } ... removed following columns... ] }); // end - $('#datagrid').datatable

here function collect edited row data form , update table data. neither of final 2 lines work expected. table update new data in expected columns createdcell button not populated.

$("body").on("click", "#btnsavedata", function (e) {     // row being edited has class     var row = $(".editing");     var data = sitetable.row(row).data();      data.site = $("#site").val();     data.offsetx = $("#offsetx").val();     data.offsety = $("#offsety").val();     data.directionname = $("#directionname").val();     data.centeringname = $("#centeringname").val();     data.structurename = $("#structurename").val();     data.source = $("#source").val();      $(row).removeclass("editing")      //sitetable.row(row).data(data).draw();     sitetable.row(row).invalidate().draw();  });

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
