Aaron Jorbin is right.That code will definitely work. I am using Infinite scroll masonry.I just added the lines posted by him and it worked.

[ Moderator Note: Please post code or markup snippets between backticks or use the code button. ]

function( newElements ) {
        // hide new items while they are loading
        var $newElems = $( newElements ).css({ opacity: 0 });
        // ensure that images load before adding to masonry layout
        $newElems.imagesLoaded(function(){
          // show elems now they're ready
          $newElems.animate({ opacity: 1 });
          $container.masonry( 'appended', $newElems, true );
          addthis.toolbox('.addthis_toolbox');
          addthis.counter('.addthis_counter');
          addthis.init();
        });
      });

Thanks Aaron Jorbin.
