Buddypress and youtube iframe API

I'm trying to implement controls to any video in the activity stream. It seems to work (for the last video post) but when I click on the "load more" button, new posts are empty.

This is my reference code:

        //Load player api asynchronously.
        var tag = document.createElement('script');  
        tag.src = "https://www.youtube.com/iframe_api";  
        var firstScriptTag = document.getElementsByTagName('script')[0];  
        firstScriptTag.parentNode.insertBefore(tag, firstScriptTag); 

       <div class="video-container">
        <div data-id="olBOo_S5AHY"></div>
        </div>
        <div class="video-container">
            <div data-id="3IXKIVZ9T-U"></div>
        </div>
        <div class="video-container">
            <div data-id="LAQDcnwwspQ"></div>
       </div>

    function onYouTubePlayerAPIReady() {
        var players = document.querySelectorAll('.video-container div')
        for (var i = 0; i < players.length; i++) {
            new YT.Player(players[i], {
                playerVars: {
                    'autoplay': 0,
                    'modestbranding': 1,
                },
                videoId: players[i].dataset.id
            });
        }
    }
