How to bind dynamic columns in ADF table to view object

Question

In the below piece of code i am trying to bind a dynamically added column to my newly added attribute in view object, but the value expression does not set the value of this attibute in the view object please help on what is wrong in this code ??
<af:table value="#{bindings.ViewObj1.collectionModel}" var="row"
rows="#{bindings.ViewObj1.rangeSize}"
emptyText="#{bindings.ViewObj1.viewable ? 'No rows yet.' : 'Access Denied.'}"
fetchSize="#{bindings.ViewObj1.rangeSize}"
filterModel="#{bindings.ViewObj1Query.queryDescriptor}"
queryListener="#{bindings.ViewObj1Query.processQuery}" varStatus="vs"
selectedRowKeys="#{bindings.ViewObj1.collectionModel.selectedRow}"
rowSelection="single"
binding="#{backingBeanScope.backing_createDTpg1.table1}"
id="table1"
columnSelection="single"
partialTriggers="::addCol ::addColAfter ::addColBefore ::removeCol ::addRow ::addRowAfter ::addRowBefore ::removeRow ::addAction ::addActionAfter ::addActionBefore ::deleteAction :::dialog1 :::d1"
allDetailsEnabled="true" verticalGridVisible="false"
horizontalGridVisible="true" width="100%" disableColumnReordering="true"
selectionListener="#{bindings.ViewObj1.collectionModel.makeCurrent}"
immediate="true" contentDelivery="immediate"
editingMode="clickToEdit" autoHeightRows="-1">
<af:column sortProperty="Sno" filterable="false" sortable="false"
headerText="Sno"
align="center" width="28" rowHeader="true"
inlineStyle="font-style:italic;" frozen="true"
id="sno" selected="true" headerNoWrap="true"
displayIndex="0">
<af:outputText id="ot0" value="#{vs.index+1}"/>
</af:column>
<af:column id="separatorColumn" align="center"
width="15" frozen="true" displayIndex="1"
rowHeader="unstyled" sortable="false"
filterable="false" selected="false"
inlineStyle='background-image:url("jheadstart/images/jsp_forward.png"); background-repeat:no-repeat; outline-color:InactiveCaption; outline-style:solid; outline-width:thin;'
headerText=""/>
</af:table>
DCBindingContainer dcBindings =
(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding iterBind =
(DCIteratorBinding)dcBindings.get("ViewObj1Iterator");
ViewObject decisionTableView1 = iterBind.getViewObject();
System.out.println("before getAttributeCount :"+decisionTableView1.getAttributeCount());
int counter = decisionTableView1.getAttributeCount() + 1;
AttributeDef attribute =
decisionTableView1.addDynamicAttribute("condition_" + counter);
RichColumn column = new RichColumn();
column.setId("condition_" + counter);
column.setHeaderText("condition_" + counter);
column.setNoWrap(true);
RichInputText inputtext = new RichInputText();
inputtext.setId("condition_"+counter);
inputtext.setAutoSubmit(true);
inputtext.setValueExpression("condition_"+counter,
getValueBinding("#{row.bindings.condition_" +
counter +
".inputValue}"));
column.getChildren().add(inputtext);
RichCommandImageLink headerLink = new RichCommandImageLink();
headerLink.setText("<<Select Fact>>");
headerLink.setId("conditionLink_" + counter);
column.setHeader(headerLink);
List columnList = this.table1.getChildren();
int separatorColumnIndex =
findColumnIndex(columnList, "separatorColumn");
if (columnIndex == -1 || columnIndex > separatorColumnIndex) {
columnIndex = separatorColumnIndex;
System.out.println("Column Index :" + columnIndex);
column.setDisplayIndex(columnIndex);
this.table1.getChildren().add(columnIndex, column);

Sorry Frank i could not figure out what u rtrying to say.
In my case i have ADF table with two predefined coulmns :
1 : a serial number read only column
2 : a separator coumn
I need help to bind the newly created dynamic attribute in the VO with my newly created column in the ADF table which has a input text as child.
My problem is binding the is not working properly as values entered in the Table are not reflected in the VO.
And when i insert a new column in between two columns which has already filled values the data in the rows does not shift coreespondingly..
