jQuery Grid Plugin - jqGrid

Hello,

I have this sourcecode but it does not save my new values

$("#grid").jqGrid({ url:'url_to_send.php', datatype: "xml", height: 452, colNames:['Name', 'Description','id'], colModel:[ {name:'id',index:'Name', width:250,editable:true,editoptions:{size:10}}, {name:'Description',index:'Description', width:500,editable:true,editoptions:{size:10}}, {name:'ID',index:'ID', width:10,hidden:true,key:true}], rowNum:10, rowTotal: 2000, rowList : [10,20], rownumbers: false, gridview: true, pager: '#purl_to_send', sortname: 'Name', viewrecords: true, sortorder: "asc", caption: "", editurl:"url_to_send.php?add=true",onSelectRow: function(id) {
  if (id) {
    var grid = jQuery('#grid');
    if(id !== lastsel) {
      grid.saveRow(lastsel)
        .editRow(id, true);
      lastsel = id;
    }
    else {
      grid.saveRow(lastsel);
      lastsel = -1;
    }
  }

}, cellurl: 'url_to_send?rows=10&page=1', cellsubmit:'remote', cellEdit: true });    

$("#grid").jqGrid('navGrid','#pgrid',{del:false,add:true,edit:false,search:false,cloneToTop:true});   

can anyone help me?

Best regards,
