OnItemCommand event does not fire on Repeater

After breaking my brain into species figuring out why the OnItemCommand event was not firing for my repeater, I finally come to very simple & stupid conclusion.

You need to rebind the repeater on the Page_Load event every time.
I was only binding the repeater if(!Page.IsPostBack) { // Bind Repeater }...

Binding the repeater in the Page_Load event took care of the issue.

      <asp:Repeater ID="repAvailableFilters" runat="server" OnItemCommand="repFilters_ItemCommand">

            <HeaderTemplate>

                <ul class="style-1">

            </HeaderTemplate>

            <ItemTemplate>

                <li>

                    <asp:LinkButton ID="lbtnAddFilter" runat="server" CommandArgument='<%# Eval("ID") %>'

                        CommandName="AddFilter"  ><%# Eval("Name") %></asp:LinkButton>

                        

                </li>

            </ItemTemplate>

            <FooterTemplate>

                </ul>

            </FooterTemplate>

        </asp:Repeater>
