Ajax loading issue

Hi Allan,

I'm a noob to DataTables and I am in total awe of the amazing quality of it all. Thanks for all the amazing hard work.

I want to create a table dynamically from data from a server.

Essentially I want to do this except with json from a server:
http://datatables.net/examples/data_sources/js_array.html

I've successfully used the following technique (works perfectly!!):

            var candidatesDataTable;
            $(document).ready(function() {
                $('#demo').html( '<table cellpadding="0" cellspacing="0" border="0" class="display" id="example"></table>' ); 
                $.getJSON( '/demos/candidateDataTables.json', null, function( json ) {
                    candidatesDataTable = $('#example').dataTable( json );
                });

            });

However, I just cannot get the following to work:

            var candidatesDataTable;
            $(document).ready(function() {
                $('#demo').html( '<table cellpadding="0" cellspacing="0" border="0" class="display" id="example"></table>' ); 
                candidatesDataTable = $('#example').dataTable({
			"sAjaxSource": '/demos/candidateDataTables.json'
		});
            });

Both should be the exact same right?

I get the following error with the second version:

Uncaught TypeError: Cannot read property 'asSorting' of undefined

I've see a similar thread but I couldn't understand how it fully applies:
