Sorting p-dataTable not working when p-column uses ng-template

Question

I'm trying to sort a column that has template. My understing is that when a column uses a template, the sorting should be done by responding to the sorting event.

<p-column field="activityName" [sortable]="true" (onSort)="onNameSorting($event)">
  <ng-template let-col let-activity="rowData" pTemplate="body">
   //..
  </ng-template>
</p-column>

However, when I put a breakpoint in the event handler, nothing is happening. Am I missing something?

onNameSorting(e){
  debugger;       //--> the breakpoint is not being hit
  //...
}

Thanks for helping

Edit

The breakpoint is being hit, the sorting is being performed. Yet no change is being reflected in the dataTable.

onNameSorting(e, dt){
  debugger;              //This break point is being hit now.
  if(!!e.order && e.order > 0){
     this.filteredItems = this.filteredItems
        .sort((a, b) => (a.activityName < b.activityName) ? -1 : 1);
  }else{
     this.filteredItems = this.filteredItems
        .sort((a, b) => (a.activityName > b.activityName) ? -1 : 1);
  }
}

I am assuming you are using the old prime data-table. In that version there was no (onSort)="onNameSorting($event)" binding to the p-column. Move that to the p-dataTable

Ex:-

<p-dataTable scrollable="true" [value]="_rowList" [selectionMode]="selectionMode"
             [responsive]="true" (selectionChange)="rowSelectionChange($event)"
             (click)="rowSingleClick($event)" (dblclick)="rowDoubleClick($event)" [(selection)]="_selectedEntity"
<!-- refer to the next line, above lines are bunch of attributes -->
             (onSort)="sortData($event, dt)"[sortField]="sortField" [sortOrder]="sortOrder" #dt>
<p-column field="activityName">
  <ng-template let-col let-activity="rowData" pTemplate="body">
   //..
  </ng-template>
</p-column>
</p-dataTable>

Suggestion: They have launched the new PrimeNg Turbo table. Its much easier and faster.
