I have a checkbox column inside a TemplateDataField, I would like to have ItemCommand event to be fired when I check/uncheck the checkbox column. My code is as below, but the item command event does not fire.

<ig:WebDataGrid ID="grdAdditions" runat="server" Width="100%"  
                                    EnableDataViewState="true" EnableAjax="false" EnableAjaxViewState="false"
                                    AutoGenerateColumns="false" DataKeyFields="AdditionID" ShowFooter="true"
                                    onitemcommand="grdAdditions_ItemCommand">

<Columns>
                                        <ig:TemplateDataField Key="Cleared" Header-Text="Clear">
                                            <ItemTemplate>
                                                <asp:CheckBox runat="server" ID="chkCleared" AutoPostBack="true"
                                                Checked='<%# DataBinder.Eval(((Infragistics.Web.UI.TemplateContainer)Container).DataItem, "IsCleared") %>' />
                                            </ItemTemplate>
                                        </ig:TemplateDataField> 

</Columns>

</ig:WebDataGrid>
