how can I add dynamic columns to datatable

[tavishiChat]

my code goes like this:
$scope.options = {
rowHeight: 50,
headerHeight: 50,
footerHeight: 50,
scrollbarV: false,
columns: alarmTableColumns,
selectable: true,
multiSelect: true,
resizable:true,
width:1350,
cellRenderer:true,
group:false,
columnMode: 'flex'

    };

Here I am fetching the alarmTableColumns by a rest call.
Problem : when I declare this options at the end of my restcall (in a callback function) so that my alarmTableColumns are fetched, I get several errors for datatable.js for eg. TypeError: Cannot read property 'length' of undefined
at DataTableController.transposeColumnDefaults ..etc.

May be it is too late, but for others who still look for an option, i added the dtable in the controller only after the rest call is completed and it is working fine for me.

var el = $compile('<dtable options="options" rows="dataMatrix" expanded="expanded" on-tree-toggle="treeToggled(cell)"></dtable>')($scope);
      $('#perm-matrix-table').append(el);
