I am trying to have two Javascript functions that are being called as soon as a user selects a date from a p:calendar.

Unfortunately, the onchange event is only being processed if the user types a date manually in the text field and tabs forward. The onselect event is not being fired at all.

The xhtml is as follows:

```
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:p="http://primefaces.org/ui">
<h:head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    <h:outputScript library="js" name="custom.js" target="body" />
</h:head>
<h:body>
    <p:log />
    <h:form id="someForm">
        <p:panelGrid columns="2">
            <p:outputLabel for="myCalendar" value="Date: " />
            <p:calendar id="myCalendar" onchange="alertDateSelected()" onselect="alertSelectEvent()" showOn="button" />
        </p:panelGrid>
    </h:form>
</h:body>
</html>    

```

The Javascript code for the onselect and onchange events:

```
function alertDateSelected() {
    PrimeFaces.info('Selected date from p:calendar');
}

function alertSelectEvent() {
    PrimeFaces.info('Clicked p:calendar date selection button');
}

```

Is there a possibility to hook to the onchange/onselect event on p:calendar; e.g. if the user selects a date from the calendar panel or via the "Today" button? If so, what am I doing incorrectly?
