How to retain the new value from a SELECT ? 

I have been experimenting with the edittype 'select' in jqGrid.

The example http://www.trirand.com/blog/jq.....qgrid.html - Input Types works, except that the values selected are overwritten when you select a new row.
The restoreRow function overwrites the new value. 
If I comment out the restoreRow function, the value remains, but the select box is still visible, and the row remains selected.

I would like the new value to 'stick', but still want the select box to disappear and the row to visually lose focus (i.e. no longer highlighted).  

How should this be coded? I tried to add saveRow (see below) but it didn't work.

onSelectRow: function(Id){
                    if(Id && Id!==lastsel2){
                    
      
                    // saveRow : function(rowid, succesfunc, url, extraparam, aftersavefunc,errorfunc, afterrestorefunc)
                    jQuery('#list4').jqGrid('saveRow',Id); // did not work.
               
                     jQuery('#list4').jqGrid('restoreRow',lastsel2);
                    jQuery('#list4').jqGrid('editRow',Id,true);
                    lastsel2=Id; }
                },
