jQuery Grid Plugin - jqGrid

when you do jqGridImport how do you add buttons to the pager? I am using the following code and nothing appears. There is no error and the data loads fine. But the refresh and search buttons dont appear.

jQuery(”#list”).jqGridImport( {
imptype : “json”,
impurl: “demo.php”,
mtype: “GET” // the type “GET” or “POST”
jsonGrid :{
config : “grid”,
data: “data”
}
});
jQuery(”#list”).navGrid(”#pager”,{refresh: true, edit: false, add: false, del: false, search: true});
