PrimeFaces <p:cellEditor> not changing value of variable - primefaces

Question

I've done some research and haven't been able to find anything that directly addresses the problem I've been having.
I have a DataTable column that is editable (by cell) and I have the ability to click on the cell, enter a new number in the cell editor box, but when I hit the cell editor closes but does not save the new value (same thing happens if you just click off and don't hit enter).
Here is the Code Snippet
<h:form>
<c:forEach items="#{extensionsBean.getPhases()}" var="phase">
<p:fieldset legend="#{phase.getPhaseName()}">
<p:dataTable value="#{extensionsBean.getActivities(phase)}" var="activity" editable="true" editMode="cell">
<p:column>
<f:facet name="header">
<h:outputText value="Actual Hours"/>
</f:facet>
<p:cellEditor>
<f:facet name="output">
<h:outputText value="#{activity.getEstimateDetail().actualHours}"/>
</f:facet>
<f:facet name="input">
<h:inputText value="#{activity.getEstimateDetail().actualHours}" />
</f:facet>
</p:cellEditor>
//the rest of the closing tags are present
Any suggestions would be great! For the record, I have basically the exact same setup in a different xhtml page and I'm able to edit each of the cells without a problem. Not sure what's causing this one to bug out on me.

Answer 1

Add Ajax event cellEdit and store the values

Answer 2

Add ajax event celledit and where do you want save the value you can save it.
Code is below in my project
Xhtml page(Primefaces):
<p:dataTable var="my" value="#{java.custom_info}" editMode="cell" editable="true" style="font-size: 12px">
<p:ajax event="cellEdit" listener="#{java.custom_detail}"/>
<p:column style="background: white">
<h:outputText value="First Name"/>
</p:column>
<p:column style="background: white">
<p:cellEditor>
<f:facet name="output"> <h:outputText value="#{my.first}"/> </f:facet>
<f:facet name="input"><p:inputText value="#{my.first}" placeholder="Enter First Name" style="width:93%"/></f:facet>
</p:cellEditor>
</p:column>
</p:dataTable>
Java Class
public void custom_detail(CellEditEvent event){
String old_str = (String) event.getOldValue();
String first_name = (String) event.getNewValue();
System.out.println("update method reached..."+first_name);
FacesContext fc = FacesContext.getCurrentInstance();
HttpSession session = (HttpSession) fc.getExternalContext().getSession(false);
Query db = new Query();
Customer bean = new Customer();
if(session!=null){
if(((String)session.getAttribute("login"))!=null){
Calendar currentDate=Calendar.getInstance();
SimpleDateFormat format=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String datenow=format.format(currentDate.getTime());
session.setAttribute("firstname", first_name);
session.setAttribute("modified_date",datenow);
bean.setFirst(first_name);
bean.setUsrid((String)session.getAttribute("user"));
bean.setUsr_modified(datenow);
db.update_personalinfo(bean);
}
}
}
