I have a link button in a repeater control. the li element is drag and droppable using jquery. when the page loads the the link button works perfectly, the jquery that is attached and the server side code both execute. when I perform a drag and drop then click on the link button it doesn't not fire. when i click it a second time it does fire. If i perform 2 or drag and drops in a row the link button doesn't fire a as many drag and drops as i before it will fire. for example if if perform 3 drag and drops then it will take about 3 click before the events are fired.

<asp:Repeater ID="rTracks" runat="server" OnItemDataBound="rTracks_ItemDataBound" EnableViewState="true">
                <ItemTemplate>
                    <li onclick="testclick();" class='admin-song ui-selectee <asp:Literal id="ltStatusClass" runat="server" />' mediaid="<%# Eval("MediaId") %>" artistid="<%# Eval("tbMedia.tbArtists.id") %>"><span class="handle"><strong>
                        <%--<%# int.Parse(DataBinder.Eval(Container, "ItemIndex", "")) + 1%>--%><%# Eval("SortNumber")%></strong><%--0:03--%></span> <span class="play"><span class="btn-play">&nbsp;</span></span> <span class="track" title="<%# Eval("tbMedia.Title") %>">
                            <%# Eval("tbMedia.Title") %></span> <span class="artist">
                                <%# Eval("tbMedia.tbArtists.Name") %></span> <span class="time" length="<%# Eval("tbMedia.Length") %>">
                                    <asp:Literal ID="ltRuntime" runat="server" /></span> <span class="notes"><span class="btn-notes">
                                        <asp:Literal ID="ltNotesCount" runat="server" /></span></span> <span class="status">

                                                    <%--<span class='<asp:Literal id="ltStatusClass2" runat="server" Text="btn-del" />'>--%>
                                                    &nbsp;<%--</span>--%></asp:LinkButton></span></span> </li>
                </ItemTemplate>
            </asp:Repeater>

I have onclick event on the li element, when the mouse is clicks the link button the li onclick event is fired even when linkbutton event doesnt fire. My question is if the li captures the event y doesnt the event fire on the linkbutton? What would be stopping the event?
