Getting values of custom datagridcolumn renderers

[Kyle McKnight]

I have a DataGrid set up like so:
<mx:DataGrid id="ticketListDataGrid"
dataProvider="{_ticketList}">
<mx:columns>
<mx:DataGridColumn width="220"
dataField="@package_name"
headerText="Package Name"
sortable="false" />

<mx:DataGridColumn width="166"
dataField="@barcode"
headerText="Ticket Barcode"
sortable="false" />

<mx:DataGridColumn width="100"
headerText="Ticket Blocked"
sortable="false"
itemRenderer="foo.bar.CustomCheckBox" />

<mx:DataGridColumn width="210"
headerText="Reason"
sortable="false"
itemRenderer="foo.bar.CustomComboBox" />
</mx:columns>
</mx:DataGrid>

On a submit I'd like to read the values of each CustomCheckBox and
CustomComboBox. What is the easiest way to get those values?

Thanks!
