checkLastPage not working when retrieving JSON

Nobody has claimed this yet.

Hello,
I'm using Infinite Scroll with this code :

``` js
$container.infiniteScroll({
path: function() {
var pageIndex = this.pageIndex + 1;
var url = jQuery('#posts').data('url');
url = url+pageIndex;
return url;
},
append: false,
responseType: 'text',
});

$container.on( 'load.infiniteScroll', function( event, response ) {
var data = JSON.parse( response );
$container.append( data.content );
});
```

But, when "/getLastPost" url is returning a blank JSON, infinite scroll is not detecting that empty result and is still trying to load the next page.

How can I fix this ?

Start with the shown infiniteScroll configuration, especially the path callback and the load.infiniteScroll handler, and reproduce the behavior against an endpoint that returns blank JSON for /getLastPost. Check how checkLastPage handles responseType: 'text' and the parsed response; done means an empty final response does not trigger another page request.
