cell template in angular grid not visible in pdf

Question

I am using ui-grid and want to export the table data in PDF through grid menu.

   $scope.gridOptions = {
         enableGridMenu: true,
         columnDefs: [
              {
                name: "Group",
                cellTemplate: '<div ng-if="row.entity.unit_GROUP">{{row.entity.unit_GROUP.description}}</div><div ng-if="!row.entity.unit_GROUP">No Group Assigned</div>'
              }
            ]
        }

This is shown in cell but when i eport the pdf through grid menu option.all the data except this group columns is exported and visible in grid.

My question is how can i make the data of grid visible which is shown in conditional cell template in columnDefs.

EDITL(added an example):

This plunker can show the problm in which "export all data as pdf" is not showing the column with conditional template(Married);
