在AJAX数据成功后加载JavaScript

Question

I begin with jQuery and I'm trying develop a web audio player using jQuery, AJAX & PHP,

I have a problem with loading jQuery script included in my DOM after the success of AJAX.

When I receive my data via AJAX, the included scripts in the DOM does not respond.

There is my code:

1: I send my data vi onclick link to AJAX script :

<a href="" onclick="getfile('<?php echo $file; ?>'); return false;"><?php echo $file?></a> 

2- AJAX receive my data with success via this function:

function getfile(audio) {
    $.ajax({
        type: 'POST',
        url: 'script.php',
        data: {
            song: audio
        },
        success: function(data) {
            $('#playlist1').html(data); // I get data with sucess in playlist1 div but player.js which is supposed to read the link that I got from PHP script is not loaded 
        },
    });
}

I tried to put player.js in getScript before AJAX it work but I have a lot of bugs when I click in another link.

My question is: how can I load all my included scripts when the AJAX request completes? I heard about live function, but I don't know how to integrate live() in my case.
