jQuery Grid Plugin - jqGrid

Hello,

I want update my database on mysql after update data on my grid.

I write this code, but it do nothing except bugging firefox

onSelectRow: function(invid){
            if(invid && invid!==lastsel){
                jQuery('#mygrid').restoreRow(lastsel);                   

                jQuery('#mygrid').saveRow(invid,'/paiement/traitement/mise_a_jour_db.php',{'name:'invid',name:'invdate',name:'name',name:'amount',name:'tax',name:'tax',name:'total',name:'note'});                       
                jQuery('#mygrid').editRow(invid,true);               
                lastsel=invid;   

             }
