Linking ItemCommand in Datagrid embedded in DataList

We have a DataGrid embedded in a DataList.  The DataList can display mulitple records (if present) and the DataGrid displays children records of the parent.  We want to be able to provide  delete function for the child records and have added the following column to the <Columns>

<asp:TemplateColumn HeaderText="Delete" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" ItemStyle-Width="40px">
    <asp:ImageButton ID="btnDelete" ImageUrl="~/images/delete.gif" Runat="server" AlternateText="Delete" CommandName="Delete" CommandArgument='<%#DataBinder.Eval(Container.DataItem,"UserID")+","+DataBinder.Eval(Container.DataItem,"CustomerID")+","+DataBinder.Eval(Container.DataItem,"SubscriptionID")%>'>

The DataGrid does not display in the designer, so we are attempting to bind the ItemCommand event handler in the DataList ItemDataBound event

BulkSubscriptionController bc = new BulkSubscriptionController ();

DataGrid grd = (DataGrid)e.Item .FindControl ("grdSubscribedUsers");
grd.DataSource = bc.GetBulkSubscriptionUsers (bsi.CustomerID,bsi.SubscriptionID);
grd.DataBind ();
grd.ItemCommand += new System.Web.UI.WebControls.DataGridCommandEventHandler(this.grdSubscribedUsers_ItemCommand);

However, the grdSubscribedUsers_ItemCommand does not fire on clicking the btnDelete image, although the form does PostBack.

Any assistance would be gratefully appreciated

Many thanks
