Param not being passed to controller

Question

I am trying to update a checkbox field on a custom object when a checkbox is checked in a list of these objects. The error is saying that no rows have been returned by my query. I am getting the object based on the ID or Name of the record clicked. My problem is I don't know which to use. I have the Name field set as an autonumber.

<apex:pageBlockTable value="{!allNotes}" var="note" id="list">
            <apex:column value="{!note.Created__c}"/>
            <apex:column value="{!note.Body__c}"/>
            <apex:column> 
                <apex:inputCheckbox value="{!note.DidyaGetterDone__c}">
                    <apex:actionSupport event="onclick" reRender="list" action="{!checkNote}">
                        <apex:param assignTo="{!noteIdValue}" value="{!note.Name}"/>
                    </apex:actionSupport>
                </apex:inputCheckbox> 
            </apex:column>
        </apex:pageBlockTable>

Controller:

public with sharing class StudyPageController {

public Notes__c note{get;set;}
public List<Notes__c> allNotes{get;set;}
public String noteIdValue{get;set;}

public StudyPageController(){
    questionList = [Select id,body__c,answer__c,Name,Type__c,Explanation__c,Category__c,A__c,B__c,C__c,D__c,E__c,pic1__c,pic2__c,pic3__c,pic4__c,pic5__c From Question__c]; 
    allNotes = [Select Name,Created__c,body__c,DidyaGetterDone__c From Notes__c];
    note = new Notes__c();
}

 public void checkNote(){
  Notes__c updateNote = [Select ID,Name,DidyaGetterDone__c From Notes__c Where Name = :noteIdValue];
  updateNote.DidyaGetterDone__c = !updateNote.DidyaGetterDone__c;
  update updateNote;
  }
}

This is the error:

List has no rows for assignment to SObject Error is in expression '{!checkNote}' in page notespage: Class.StudyPageController.checkNote: line 67, column 1

@madmax You have note as variable which is used as in apex:pageBlockTable and you also have the same variable name defined variable in controller. Please use different names. VF is considering the controller variable which has no value in name.
