jQuery Grid Plugin - jqGrid

Hi,

How do I pass a true/false using JSONString? If I pass, the true/false value as a string ie 'true' than it works.

    var response = "{page:1,total:1.0,records:1,rows:[{'id':5,'name':true}]}";

    jQuery("#gvPhoneNumbers").jqGrid({
        datatype: 'jsonstring',
        datastr : response,
        colNames:['Id','Name'],
        colModel:[
            {name:'id',index:'id', width:30},
            {name:'name',index:'name', width:150,formatter:'checkbox'},
        ],
        viewrecords: true,
        caption: ' ',
        jsonReader:{
          root: "rows",
          page: "page",
          total: "total",
          records: "records",
          repeatitems: false,
          cell: "",
          id: "0"}       
    });

Thank you

Abel
