在页面加载期间调用JqGrid，但是下次在按钮上调用它时，它不会被调用

Question

    $(document).ready(function () {
        BindGrid('', '', '', '', 1, 2, '', '', sessionStorage.UserID);

    });
    function Search() {
        $('#modal_Advance_Search').modal('hide');
        var channelselected = $('#dd_channel option:selected');
        var channelarray = [];
        $(channelselected).each(function (index, channelsel) {
            channelarray.push([$(this).val()]);
        });
        var Channel = channelarray.toString();

        var Distselected = $('#dd_dist_category option:selected');
        var Distarray = [];
        $(Distselected).each(function (index, channelsel) {
            Distarray.push([$(this).val()]);
        });
        var DistributorCategory = Distarray.toString();

        var ARNNo = "";
        var token = $("#txt_arn").tokenInput("get");
        var names = [];

        $.each(token, function (i, obj) {
            names.push(obj.name);//build an array of just the names
        });
        ARNNo = names.toString();

        sessionStorage.setItem("DistributorCategoryMaster", DistributorCategory);
        sessionStorage.setItem("ChannelCreateMaster", Channel);
        sessionStorage.setItem("ARNCreateMaster", ARNNo);

        sessionStorage.setItem("ismasterqueue", true);

        $("#hdr_name").text("Master Q");

        $("#spn_user_name").text(sessionStorage.UserName);
        $("#spn_role_name").text(sessionStorage.RoleName);

        BindGrid(ARNNo, Channel, '', DistributorCategory, 1, 2, Utility.ListSearchText, '', sessionStorage.UserID)

    }
    function BindGrid(ArnNo1, Channel1, ARNName1, DistributorCategory1, Status1, MasterQueueStatus1, SearchFilter1, MemoLevel1, UserID1) {


        $("#tbl_masterqueue").jqGrid({

            rowList: [100, 200, 300, 400, 500],
            pager: '#pager',
            sortname: 'PaymentMemoId',
            viewrecords: true,
            sortorder: "desc",
            gridview: true,
            height: '510px',
            loadonce: true,
            gridview: true

        });
        jQuery("#tbl_masterqueue").jqGrid('navGrid', '#pager', { add: false, edit: false, del: false, search: true, refresh: true },
                   {}, {}, {}, { multipleSearch: true, multipleGroup: true, showQuery: true });
    }

我在页面加载期间创建了一个绑定网格的方法，它工作正常，但是当在按钮上点击过滤/搜索时调用相同的方法时，此方法无效。我正在使用JQGrid，请帮助解决。
