how to save changes made by JUICE-UI sortable control back to list
===

I'm making an ASP.net C# website using the JUICE-UI plugin. 

I have a list of custom objects. The custom class contains a property "sequence" which represents its order in the collection(not the index!) I'm binding a repeater within a ul to a datasource to gets this list sorted by the sequence property. I've then added a juice-ui sortable control to point to the list. It works fine in so far as allowing me to drag and drop but how can i update the sequence properties of all the objects in the list to reflect the changes made?  Any advice please? Thanks a bunch.

P.S i decided to use the JUICE UI controls instead of just jQuery UI because I am real new and its very complicated for me. If your answer suggests going away from JUICE please include all relevant information, don't assume I know :) !!   


    <ul id="ul1" runat="server"  >
    <asp:Repeater ID="Repeater1" runat="server" DataSourceID="ObjectDataSource4">
    <ItemTemplate>
    <li>
    <%# DataBinder.Eval(Container.DataItem, "codeString") %>
    </li>
    </ItemTemplate>

    </asp:Repeater>

    <asp:ObjectDataSource ID="ObjectDataSource4" runat="server" 
        SelectMethod="getAllUnits" TypeName="currentSession"></asp:ObjectDataSource>

    </ul>
    
    <juice:Sortable TargetControlID="ul1" runat="server"  />
