title: jqgrid don't call successfunc after addrow
body: <p>I try to work with the jqgrid and have now the problem that the function <code>successfunc</code>, <code>aftersavefunc</code>, <code>errorfunc</code> and <code>afterrestorefunc</code> not will be called.</p>
  
  <p>My code:</p>
  
  <pre><code>$("#list-nxfeatures").jqGrid({
      url:'lib/nxfeatures.php',
      datatype: 'xml',
      mtype: 'GET',
      colNames:['Id','Name', 'Description','Default','Allow change','Nolimit'],
      colModel :[ 
        {name:'id', index:'id', width:55}, 
        {name:'name', index:'datasetid', width:150, editable:true}, 
        {name:'description', index:'featureid', width:200, editable:true}, 
        {name:'defaultvalue', index:'defaultvalue', width:80, align:'center',editable:true, edittype:"checkbox", editoptions: {value:"1:0"}}, 
        {name:'allowchange', index:'allowchange', width:100, align:'center',editable:true, edittype:"checkbox", editoptions: {value:"1:0"}}, 
        {name:'nolimit', index:'nolimit', width:80, align:'center',sortable:false,editable:true, edittype:"checkbox", editoptions: {value:"1:0"}} 
      ],
      pager: '#pager-nxfeatures',
      rowNum:10,
      rowList:[10,20,30,100],
      rownumbers: true,
      sortname: 'id',
      sortorder: 'desc',
      viewrecords: true,
      gridview: true,
      caption: 'Features',
      editurl: "lib/modifynxfeatures.php",
      height: 220,
      width: 800
    }); 
  
    jQuery("#list-nxfeatures").jqGrid('navGrid',"#pager-nxfeatures",{edit:false,add:false,del:true});
    jQuery("#list-nxfeatures").jqGrid('inlineNav', "#pager-nxfeatures", { addParams: {
        rowID: "neu3",
        addRowParams: {
            oneditfunc: function () {
                alert("edited");
            },
            successfunc: function (response) {
                alert("success");
                return true;
            },
            aftersavefunc: function (response) {
                alert("aftersave");
            },
            errorfunc: function (rowid, response) {
                alert("errorfunc");
            },
            afterrestorefunc :function (rowid) {
                alert("afterrestorefunc");
            }
        }
    }
    });
    jQuery("#list-nxfeatures").jqGrid('filterToolbar',{stringResult: true,searchOnEnter : false});
  </code></pre>
  
  <p>What is wrong on my code?
  The <code>oneditfunc</code> is work perfect.</p>
