asp:ImageButton in Gridview OnClick event not working

I've spent quite a while searching this problem, there are some other similar threads online but none have helped me fix it.

I have a GridView with an ImageButton within it, the imagebutton has an OnClick function but that event is never reached when it is clicked, below is my gridview:

<asp:GridView ID="gridBuildings" runat="server" AutoGenerateColumns="False"
              GridLines="none" ShowFooter="false" ShowHeader="false" 
              Width="100%">
    <Columns>
        <asp:TemplateField>
            <ItemTemplate>
                <asp:ImageButton runat="server" ID="cmdBuy"
                     ImageUrl="~/images/button.jpg" 
                     OnClick="ImageButton_Click"/>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

and here's the code-behind (I've removed the extra content, the response.redirect is never hit when the ImageButton is clicked)

Protected Sub ImageButton_click(ByVal sender As Object, ByVal e As ImageClickEventArgs)
    response.redirect("test.aspx")
    Dim row As GridViewRow = Me.gridBuildings.SelectedRow
    (etc ... )
End Sub

There is a form runat="server" tag in the master page, as well as an asp:UpdatePanel and an asp:AjaxScriptManager I have a feeling the problem might be something to do with a postback but just can't work it out - any help would be appreciated.

Thanks!

Make sure you are not rebinding the grid every page load. If you rebind, the event will never fire. Wrap the binding statement in an if not ispostback block.
