You can re-initialize all the scripts once again inside the AJAX success.

// Fetch the scripts
var $scripts;
if ( $scripts.length ) $scripts.detach();
$scripts = $dataBody.find('#document-script');

// Add the scripts
$scripts.each(function(){
        var $script = $(this), 
                scriptText = $script.html(), 
                scriptNode = document.createElement('script');
        try {
                // doesn't work on ie...
                scriptNode.appendChild(document.createTextNode(scriptText));
                contentNode.appendChild(scriptNode);
        } catch(e) {
                // IE has funky script nodes
                scriptNode.text = scriptText;
                contentNode.appendChild(scriptNode);
        }
        if($(this).attr('src') != null) {
                scriptNode.setAttribute('src', ($(this).attr('src')));
        }
});
