Forms Data Controls :: Linkbutton Within Datalist Not Working

I'm trying to get a link button within a datalist but its not working. I'm not getting any errors, the breakpoints on my c# are just not being reached.

<asp:DataList ID="propertyDataList" runat="server" EnableViewState="False">
<ItemTemplate>
<asp:LinkButton runat="server" CommandName="EmailSeller" CommandArgument='<%# Eval("email") %>' ID="EmailSeller">Email</asp:LinkButton>
</ItemTemplate>
</asp:DataList>

C#

protected void propertyDataList_ItemCommand(object source, DataListCommandEventArgs e)
{
if (e.CommandName == "EmailSeller")
{
Response.Redirect("test.aspx");
}
}
