jQuery Grid Plugin - jqGrid

I use this code to create a premanent serach box and it works great.

        // set searching defaults
        $.extend($.jgrid.search, {caption:"Search Functionality and Parameters for the NFIRS Code Details", multipleSearch: true, /*multipleGroup: true,*/ overlay: 0});
        // create the searching dialog
        $grid.jqGrid('searchGrid');
        var gridSelector = $.jgrid.jqID($grid[0].id); // 'list'
        $searchDialog = $("#searchmodfbox_" + gridSelector);
        $gbox = $("#gbox_" + gridSelector);
        //alert($gbox)
        // hide 'close' button of the searchring dialog
        $searchDialog.find("a.ui-jqdialog-titlebar-close").hide();
        // place the searching dialog above the grid
        $searchDialog.insertBefore($gbox);
        $searchDialog.css({position: "relative", zIndex: "auto", float: "center", width: 1100})
        $gbox.css({clear:"left"});

HOWEVER, I can't use this code to clear the search fields.

$("#gs_" + $.jgrid.jqID(k), $("#code_grid").get(1).grid.hDiv).val("");

CAN SOMEONE PLEASE HELP ME RESOLVE THIS ISSUE?
