Display message when there is no post

Hi all,

Just want to get some help on this topic.

How do I display message “No Post available” when no post in the category.

I have try the solution given by dcooney, but not success

$.fn.almEmpty = function(alm){
	var el = $(alm.content);
	el.append('<li>Nothing found in this Ajax Load More query</li>');
	//console.log(alm);
};

I have upload the site if any one can take a look and help out please.

Web page URL

The .js file URL

If you can please have a look and let me know where I need to change the code that would be great.
