Why cannot populate value in nested:select onchange field???

Question

<div class="labelledField">
<nested:select styleId='<%="pvqList.questions"+index.intValue()+".questionDropDown"%>' property="questionDropDown" styleClass="formFieldSelect" tabindex='<%=""+((5*index.intValue())+1)%>' onchange="togglePVQ('customQuestion<%=index.intValue()%>FieldLabelPair','<%=index.intValue()%>');return false;">
     <option value=""><cibc:text key="ref.text.app.changePVQStep1.dropdown.selectAQuestion"/></option>
     <option value="">--------------------</option>
     <option value="CUSTOMQUESTION">Create Custom Question</option>
     <option value="">--------------------</option>
     </nested:select>
     <a href="# tabindex='<%=""+((5*index.intValue())+2)%">' onclick="togglePVQ('customQuestion<%=index.intValue()%>FieldLabelPair','<%=index.intValue()%>');return false;">
     try</a>
     </div>
Outside nested:select, onclick can correctly populate to onclick="togglePVQ('customQuestion1FieldLabelPair','1');return false;"
but onchange in nested:select cannot populate, it only show :
onchange="togglePVQ('customQuestion<%=index.intValue()%>FieldLabelPair','<%=index.intValue()%>');return false;"
why??? How to solve it??
please help.

Fabio,
1) what settings do you use for Default Value Type and Default Value?
2) which error is raised?
