In Angular JS how to disable column sort feature for selected columns

The angular-datatables equivalence to

aoColumnDefs: [{ bSortable: false, aTargets: [0, 4] }]

is

$scope.dtColumnDefs = [
   DTColumnDefBuilder.newColumnDef(0).notSortable(),
   DTColumnDefBuilder.newColumnDef(4).notSortable()
];

...

<table class="custom-table" dt-column-defs="dtColumnDefs" datatable="ng" dt-options="dtOptions" id="contacts-list-table"></table>

You must include DTColumnDefBuilder in the controller :

myApp.controller("ListCtr", ['DTOptionsBuilder', 'DTColumnDefBuilder',
    function(DTOptionsBuilder, DTColumnDefBuilder) {
       $scope.dtOptions = DTOptionsBuilder.newOptions().withDOM('C<"clear">lfrtip');
       $scope.dtColumnDefs = [
          DTColumnDefBuilder.newColumnDef(0).notSortable(),
          DTColumnDefBuilder.newColumnDef(4).notSortable()
       ];
    }
])
