Trigger AJAX on the Select All Check boxes Primefaces DataTable

Question

I need to execute a backing bean method when the user selects that checkbox on the top (the one that selects all the check-boxes).

I'm talking about this one:

As for the regular check boxes:

I was able to execute a backing bean method by adding the following tags inside the <p:dataTable><p:dataTable/>:

<p:ajax event="rowSelectCheckbox" listener="#{beanJanela.atualizaVariacaoSaldo}" update="variacaoSaldo" />
<p:ajax event="rowUnselectCheckbox" listener="#{beanJanela.atualizaVariacaoSaldo}" update="variacaoSaldo" />

It almost seems like it would be a matter of just adding another <p:ajax .. /> with an event like rowSelectAllCheckbox, unfortunately that event does not exist.

So how would I go about executing #{beanJanela.atualizaVariacaoSaldo} when that first checkbox is selected? Thank you.

The Primefaces User Guide (Version 6.2), page 181 offers the following event on p:datatable:

Event: toggleSelect
Listener Parameter: org.primefaces.event.ToggleSelectEvent
Fired: When header checkbox is toggled.

So try using

<p:ajax event="toggleSelect" .../>

on the datatable.
