Pagecontainer: load event callback receives empty ui object

[robdiciuccio]

The pagecontainerload event callback is not passed a valid "ui" object.

Test page: http://jsbin.com/huvoraba/53

Expected: pagecontainerload callback receives a valid "ui" object containing properties including toPage, prevPage, xhr, etc.

Actual: pagecontainerload callback receives an empty "ui" object.

Steps to reproduce:

1. Bind a callback to the pagecontainerload event and note that the "ui" object is empty

$(document).on( "pagecontainerload", function( event, ui ) { console.log('pagecontainerload', event, ui); } );
