SetValue of textfield in RowExpander - Cannot read property 'setValue' of undefined

[atroul]

I am trying to set the value of a textfield in a rowexpander in codebehind or in js on AfterRender event listener, but I get

Cannot read property 'setValue' of undefined

Here is the textfield in the rowexpander:

<ext:TextField runat="server" Name="notedown" FieldLabel="Note Under" ID="fnotedown">
       <Listeners>
              <AfterRender Handler="if (form.record.data.Lid != null && form.record.data.Lid != '' )
              {
                 setNoteUnder_js(form.record.data.id);
              }" />
                                                                    
       </Listeners>
    </ext:TextField>

JS:

var setNoteUnder_js = function (fieldid){
                #{DirectMethods}.setNoteUnder(fieldid,{
                    success: function (result) {
                        #{fnotedown}.setValue(result); //undefined error
                    }
                });
            }

Direct Method in Code Behind:

[DirectMethod]
	public string setNoteUnder(int fieldid)
	{
		DAL.CDMADataContext dc = new DAL.CDMADataContext();

		var field = (from f in dc.CFormFields
					 where f.cid == cid && f.id == fieldid
					 select f).FirstOrDefault();

		string units = null;

		if (field.Lid != null && field.Lid != "")
		{
			
			 units = units + " Gender: " + field.text1 + " Unit: " + field.text2;

			 fnotedown.SetValue(units); //undefined error

			 return units;
			

		}
		return null;
	}

replace


#{fnotedown}.setValue(result); //undefined error


with


App.fnotedown.setValue(result);


see if that helps
