UpdatePanel内的javascript无法回发

Question

我有一个包含表的UpdatePanel。我正在调用javascript函数来填充表数据。首次呈现页面时，一切工作正常。但是，发生回发时不会显示数据。方法DisplaySvcAgmtFeaturesAndOperational位于单独的.js文件中。我该如何解决？

<form id="PageForm" runat="server" style="WIDTH: 98%; margin: 1px;">
        <asp:ScriptManager id="scriptManager" runat="server">
        </asp:ScriptManager>

...
<asp:UpdatePanel ID="SummaryUpdatePanel" runat="server" UpdateMode="Conditional">
...

<ItemTemplate>

    <tr>
    <td>
        <% if (!ServiceOrderReadOnly) {%>
             <asp:ImageButton ID="DeleteButton" CommandName="Delete" ImageUrl="~/_imgs/16_l_remove.gif" runat="server" Width="16px" Height="16px" OnClientClick="javascript:return confirm('Are you sure you want to delete this resource?');" />
        <%  } %>
    </td>
    <td>
      <%# Eval("serialNumber") %>: <%# Eval("name") %>&nbsp;
    </td>
    <td>
        <script type="text/javascript">
             DisplaySvcAgmtFeaturesAndOperational( <%# Eval("displayServAgmtFeatures")%>, <%# Eval("displayOperationalYesNo")%>, <%#  Eval("operational") %>, <%# Eval("emgCov") %>, <%# Eval("autoExp") %>,<%# Eval("accCov") %>, 
                  <%# Eval("expParts") %>, <%# Eval("wtrCov") %> ) 
         </script>        
    </td>                                       
    </tr>
