rich dataTable update issue - jsf

Question

I have a problem with rich dataTable
actually I populate that dataTable from a database and a made a column editable by putting an inplaceInput in it the problem is when i submit to the backing bean The values doesn't change the backing bean is populated with old values that initially populated the dataTable :
here is my JSF Code of the table:
<center>
<fieldset><rich:dataTable id="tablefiles"
value="#{fileBean.files}" var="file" rows="8"
iterationStatusVar="it">
<rich:column id="Child_Code">
<f:facet name="header">
<h:outputText value="N°tiers filiale" />
</f:facet>
<h:outputText value="#{file.child_Code}" />
</rich:column>
<rich:column id="Mother_Code">
<f:facet name="header">
<h:outputText value="Nom du groupe" />
</f:facet>
<!-- <h:inputText value="#{file.mother_Code}" />-->
<rich:inplaceInput defaultLabel="Click here to edit"
showControls="false" controlsHorizontalPosition="left"
controlsVerticalPosition="bottom" id="inplaceInput"
value="#{file.mother_Code}"
>
</rich:inplaceInput>
</rich:column>
<rich:column>
<f:facet name="header" roles="#riskuser">
<h:outputText value="Détail" />
</f:facet>
<h:commandLink action="#{fileBean.accesDetail}">

style="border:0;" title="Détail " />
<f:setPropertyActionListener target="#{fileBean.selectedFile}"
value="#{file}" />
</h:commandLink>
</rich:column>
<f:facet name="footer">
<rich:dataScroller page="#{fileBean.page}" />
</f:facet>
</rich:dataTable> <br />
<h:panelGrid columns="3" id="buttonRow">

Here is My bean code :

}
public String getId_r() {

}
public List<SRGarantieCasa> getFiles() {

return null;
}
public String search() {

files = fileService.getListeFiles();
} else {
files.clear();
files = fileService.getFile(id_r);
}
return null;
}
public String accesDetail() {
return "GCUpdate?faces-redirect=true";
}
public String saveFile() {
fileService.updateFile(selectedFile);
return "GarantieCasa?faces-redirect=true";
}
public String ajoutFile() {

*/
}
public void update()
{
for (SRGarantieCasa selectedFile : fileService.getListeFiles()){
System.out.println("GarantieCasaBean : Mother Code :"+selectedFile.getMother_Code());
fileService.updateFile(selectedFile);
}
//return "GarantieCasa?faces-redirect=true";
}
}
and here is the spring conf :
<!-- Service UI -->
