AddHandler for a control inside TemplateField

Hello,

I have a UserControl with an event. I would like to add a handler for this event in a page, to an instance of the UserControl that is inside a GridView's TemplateField.

I tried adding it as I did for an instance of the UserControl that is on the page but nothing happens. I don't get any error messages, but the event handler wont fire.

Thank you

 
Sub updateNewScope() Handles scopeChange.scopeUpdated
gvChangesOfScope.DataBind()
End Sub
