jQuery Grid Plugin - jqGrid

Hello

my grid go not reload after insert Data in row editing! What is wrong?

At first I have

...

var aftersavefunc = function(){ jQuery('#todo').trigger('reloadGrid')};

....

I use :

....

 else if (ret.status == 'b'  )
        {
jQuery("#todo").setColProp("edatum",   {editable:true}  );
jQuery("#todo").setColProp("erledigt", {editable:true}  );
jQuery("#"+id+"_edatum","#todo").datepicker({showOn: 'button', buttonImage: 'themes/selbst/images/calendar.gif', buttonImageOnly: true, dateFormat:'dd.mm.yy',changeMonth: true, changeYear: true });
jQuery('#todo').editRow   (id, true);
jQuery('#todo').saveRow   ('', '','','','',aftersavefunc,''    );

....

After insert a Date and press "enter" the aftersavefunc do not fire!

Any Ideas?
