Upon OnSelectRow, Iam trying to produce an alert from the callback function hello once saved, what am I doing wrong.(script below)

It may be that Iam a little confused as to how to use the save row API method.

Heres what I have:

jQuery("#rowed3").jqGrid('saveRow',id, hello, url, rowList, hello,hello, hello);

My Questions:

A) Do I have to have all the parameters in the saveRow method for the function to work?

B) Where does the hello(); function have to be located for it to work?

C) How can I see the ajax data being sent to the server? Meaning upon using the SaveRow function what array or data is being sent to server?

D) How to I properly use SaveRow in my script , Iam trying to get an alert() to set off within the hello function once the function SaveRow has been executed.

My Script:

$(document).ready(function() {
var lastsel;
function hello() {
    
alert("Done");    
    
}
jQuery("#rowed3").jqGrid({
       url:'http://charmednetworks.com/gri.....p',
    datatype: "json",
       colNames:['Actions','Inv No','Date', 'Client', 'Amount','Tax','Total','Notes'],
       colModel:[
        {name:'act',index:'act', width:75,sortable:false},
           {name:'id',index:'id', width:90},
           {name:'invdate',index:'invdate', width:120, editable:true},
           {name:'name',index:'name', width:100,editable:true},
           {name:'amount',index:'amount', width:80, align:"right",editable:true},
           {name:'tax',index:'tax', width:80, align:"right",editable:true},        
           {name:'total',index:'total', width:80,align:"right",editable:true},

            jQuery("#rowed3").jqGrid('saveRow',id, hello, url, rowList, hello,hello, hello);
            lastsel=id;
            alert(id);
        }
    },
    gridComplete: function(){
        var ids = jQuery("#rowed3").jqGrid('getDataIDs');
        
        for(var i=0;i < ids.length;i++){
