<apex:inputfield> of type Text Area is not working for <apex:actionSupport>

Hi,
I have TextArea field named Attendance_Notes__c on object EventBooking. I developing a pageblocktable. One column of this table is shown here
When delegate has partial attendance for a course, trainer should put a note.
The checkbox will show Text Area field to put notes. 
<apex:Column id="pa">
         <apex:facet name="header">Partial Attendance</apex:facet>
         <apex:inputCheckbox id="isPartialAttendance" value="{!ebrecs.EventBooking['Partial_Attendance_Flag__c']}" selected="false" rendered="{!ebrecs.isCheckBoxShow}">
                  <apex:actionsupport status="submitStatus" event="onclick" action="{!saveValues}" reRender="pa,pm">
                           <apex:param assignto="{!index}" name="param1" value="{!ebrecs.index}"/>
                  </apex:actionsupport>
        </apex:inputCheckbox>
        <apex:inputfield id="inputpa" label="Notes" value="{!ebrecs.EventBooking['Attendance_Notes__c']}" rendered="{!AND(if(ebrecs.EventBooking['Partial_Attendance_Flag__c']==true,true,false),ebrecs.isCheckBoxShow)}">
                 <apex:actionsupport immediate="true" status="submitStatus" event="onchange" action="{!saveValues}" reRender="pa,pm">
                         <apex:param assignto="{!index}" name="param1" value="{!ebrecs.index}"/>
                </apex:actionsupport>
       </apex:inputfield>
</apex:Column>
when inputfield is updated(event="onchange") with notes, action - saveValues on actionsupport should be invoked, which is not invoking now.
It is working fine for all other field type from other column
Could you please help ?

Best Regards,

Rahul

Try adding an <apex: actionRegion> tag before the input field 
<apex:Column id="pa">
	<apex:facet name="header">Partial Attendance</apex:facet>
		<apex:inputCheckbox id="isPartialAttendance" value="{!ebrecs.EventBooking['Partial_Attendance_Flag__c']}" selected="false" rendered="{!ebrecs.isCheckBoxShow}">
			<apex:actionsupport status="submitStatus" event="onclick" action="{!saveValues}" reRender="pa,pm">
				<apex:param assignto="{!index}" name="param1" value="{!ebrecs.index}"/>
			</apex:actionsupport>
		</apex:inputCheckbox>
		
		<apex: actionRegion>
			<apex:inputfield id="inputpa" label="Notes" value="{!ebrecs.EventBooking['Attendance_Notes__c']}" rendered="{!AND(if(ebrecs.EventBooking['Partial_Attendance_Flag__c']==true,true,false),ebrecs.isCheckBoxShow)}">
				<apex:actionsupport immediate="true" status="submitStatus" event="onchange" action="{!saveValues}" reRender="pa,pm">
					<apex:param assignto="{!index}" name="param1" value="{!ebrecs.index}"/>
				</apex:actionsupport>
			</apex:inputfield>
		</apex:actionRegion>
</apex:Column>
