ValueChangeEvent is getting fired on scrolling down table

Question

Hi,
We are trying to implement a checkbox based selection of rows on a table using JDeveloper 11.1.1.3.0.
We've created a Boolean attribute in EO and based on the EO, we've created the VO. While creating the table using VO, we are converting the Boolean attribute to "af:selectBooleanCheckbox".
Now the issue is on UI. When we scroll down the table, ValueChangeEvent for the checkbox is getting fired without even selecting the checkbox.
Please let me know why it is behaving like this.
Thanks in advance.
Regards

jsf code:
<af:column sortProperty="Selected" sortable="true"
headerText="Selected" id="c32"
inlineStyle='#{(row.Selected)?"background-color: #ffaaaa":""};'
width="105">
<af:selectBooleanCheckbox value="#{row.bindings.Selected.inputValue}"
valueChangeListener="#{viewScope.InstWorkFlowBean.ckeckBoxValueChangeAction}"
id="sbc1" autoSubmit="true"/>
</af:column>
Managed Bean:
public void ckeckBoxValueChangeAction(ValueChangeEvent valueChangeEvent) {
DCIteratorBinding oeInstWorkflScrhVO1ItrBndng =
ADFUtils.findIterator("OeInstWorkflScrhVO1Iterator");
RowSetIterator oeInstWorkflScrhRsltSet =
oeInstWorkflScrhVO1ItrBndng.getRowSetIterator();
RowKeySet rowkeyset = masterTableRef.getSelectedRowKeys();
Boolean newValue = (Boolean)valueChangeEvent.getNewValue();
Iterator itr = rowkeyset.iterator();
while (itr.hasNext()) {
Key key = (Key)((List)itr.next()).get(0);
Row currentRow = oeInstWorkflScrhRsltSet.getRow(key);
if (currentRow != null && newValue) {
if (selectedIds.length() > 0) {
selectedIds =
selectedIds + "," + currentRow.getAttribute("Id");
} else {
selectedIds = selectedIds + currentRow.getAttribute("Id");
if (currentRow != null && (!newValue)) {
String tempString1 =
selectedIds.substring(0, selectedIds.indexOf(currentRow.getAttribute("Id").toString()));
String tempString2 = "";
if (selectedIds.contains(",")) {
tempString2 =
selectedIds.substring(selectedIds.indexOf(currentRow.getAttribute("Id").toString()) +
currentRow.getAttribute("Id").toString().length() +
1);
selectedIds = tempString1 + tempString2;
oeInstWorkflScrhRsltSet.reset();
System.out.println(selectedIds);
OperationBinding executeWithParams =
ADFUtils.findOperation("ExecuteWithParams");
executeWithParams.getParamsMap().put("instWfIds", selectedIds);
executeWithParams.execute();
AdfFacesContext.getCurrentInstance().addPartialTarget(childTableRef);
AdfFacesContext.getCurrentInstance().addPartialTarget(componentHeader);
}
