You can re-initialize all the scripts once again inside the AJAX success.
// Fetch the scripts
scripts = '';
if ( scripts.length ) scripts.detach();
scripts = response.find('script');
// Add the scripts
scripts.each(function(){
var script = jQuery(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(jQuery(this).attr('src') != null) {
scriptNode.setAttribute('src', (jQuery(this).attr('src')));
}
});
