How Do I Disable Same Row Repeating In Yii Infinite Scrolling?

Yii 1.1 General Discussion

After adding infinite scrolling in my web page I found sometimes it’s showing same row on another pages. I have used following code-




<?php 

$this->widget('ext.yiinfinite-scroll.YiinfiniteScroller', 

array( 'contentSelector' => '#posts',

 'itemSelector' => 'div.post',

 'loadingText' => 'Loading...',

 'donetext' => 'Data loading end', 

'pages' => $pages, 

)); 

?>

How do I disable repeating same row?
