How do you remove all content within an element including the javascript

I'm using ajax to get the content (html, css, javascript) from another file. Everything works perfected initially; however, if I run this ajax request a second time, all the javascript from the first call remains saved on the dom, so any .on("click") functions get executed twice. I've tried $("#contentHolder").empty() with no success. Also, I do need to execute the ajax call more than once (I can't call it once, save the content, then just .hide/.show as needed).

$.ajax({    type: "GET",    url: "page.php",    dataType: "html",    success: function(data){        $("#contentHolder").html(data);    }});
