Update DataTable after cell edit not working in primefaces - jsf

Question

I have a datatable includes some cell for edit, and these cells are disabled in specific conditions and after an other cell edition will be enabled.
My problem is after the edit, the new data stored in the database but the datatable not updated directly, it will be updated after reloading the page.
All what I want is how can I make the hole datatable updated after the edit or making the page reloaded
and here is my code:
<h:form id="process">
<p:remoteCommand name="onCellEdit" update=":process:ListC" />
<p:dataTable id="ListC"
value="#{recruitmentProcessMB.candidateListInProcess}"
var="candid" rowKey="#{candid.idCandidate}"
style="border:0px; " paginator="true"
paginatorTemplate="{PreviousPageLink} {NextPageLink} {RowsPerPageDropdown}"
rowsPerPageTemplate="3,5,10" paginatorPosition="top"
rows="10" editable="true" editMode="cell">
<f:facet name="footer" >
<h:outputLabel value="Valider processus pour le Manager:" style="display: inline-block;"/>
