Update variable retrieved form the database after submitting - jsf

Question

I have 2 classes Games and Fouls, there are lot of fouls in a game. The user sends a parameter with the game id to find the game he want and after that the currentGame variable is created.Its type is Game. I have a datatable which prints the fouls in the current game
The setCurentGame setter is called form the body of the page onload.
so far everything works okay, but when I add a new foul, is not added to the datatable, my assumption is that the game was already retrieved (because current game was created before) so the new foul is in the database and not in the Game currentGame.
Is there any way that i can update the currentGame every time a foul i added?
I have tried refreshing the page and even to call the seeter again after creating the foul but nothing worked
The datatable looks like this:
<p:dataTable id="datalist" value="#{gameController.currentGame.foulCollection}" var="item">
<f:facet name="{exporters}">
</f:facet>
<p:ajax event="rowSelect" update="createButton viewButton editButton deleteButton"/>
<p:ajax event="rowUnselect" update="createButton viewButton editButton deleteButton"/>
<p:column width="32" sortBy="#{item.id}" filterBy="#{item.id}">
<f:facet name="header">
<h:outputText value="#{bundle.ListFoulTitle_id}"/>
</f:facet>
<h:outputText value="#{item.id}"/>
</p:column>
<p:column sortBy="#{item.quarter}" filterBy="#{item.quarter}">
<f:facet name="header">
<h:outputText value="#{bundle.ListFoulTitle_quarter}"/>
</f:facet>
<h:outputText value="#{item.quarter}"/>
</p:column>
<p:column sortBy="#{item.foultime}" filterBy="#{item.foultime}">
<f:facet name="header">
<h:outputText value="#{bundle.ListFoulTitle_foultime}"/>
</f:facet>
<h:outputText value="#{item.foultime}"/>
</p:column>
<f:facet name="footer">
<p:commandButton id="createButton" icon="ui-icon-plus" value="#{bundle.Create}" actionListener="#{foulController.prepareCreate}" update=":FoulCreateForm" oncomplete="PF('FoulCreateDialog').show()"/>
</f:facet>
</p:dataTable>

Answer 1

It seems your setCurrentGame method will not be called, you can manually call it in your create() method to update the current game object from the database after the foul is created.
