I can't access the controls in the repeater from the code behind

<asp:Panel ID="pnlRecipeComments" runat="server" CssClass="panels" GroupingText="RecipeCommemts" > <asp:Repeater ID="rptComments" runat="server" > <ItemTemplate> <div id= "comments"> <asp:Label ID="lblTime" runat="server" Text= '<%# "Posted on:" + Eval("postedTime") + "<br/> By " + Eval("name") %>' CssClass="commentsPostedTime"></asp:Label> <asp:Label ID="lblComment" runat="server" Text= '<%# Eval("comment") %>' ></asp:Label> </div> <asp:Button ID="btnEditComment" runat="server" Text="EditComment" /> </ItemTemplate> </asp:Repeater> ...
