此JavaScript / jQuery代码是否会在ie8或其他浏览器中泄漏？

Question

I spent a lot of time reading about memory leaks. I'm confused because what was true for ie6 is not true anymore for ie8 or newer browsers. From what I understand, this code could/would leak because, in a function, I created a DOM element on which I bind an event. Is my understanding correct? If so, would the code in comments would leak, too? If it does, what would be the best approach to not have a leak?

function somefunc() {
    var $CodeInstallation, $selInstallation;

    $CodeInstallation = jQuery(<...some form tag...>);

    $selInstallation = jQuery(
        '<input value="select"' +
        ' type="button" name="selInstallation" ' +
        ' id="idSelInstallation"/>')
        .appendTo($CodeInstallation.parent());

    // should I do that instead  ???
    /*
    jQuery('<input value="select"' +
       ' type="button" name="selInstallation" ' +
       ' id="idSelInstallation"/>')
       .appendTo($CodeInstallation.parent());
    $selInstallation = jQuery('#idSelInstallation');
    */

    $selInstallation.click( function() {
        alert('click!');
    }); // click
}

感谢Pointy和KevinB。答案是否定的，原因是jQuery处理事件而不是附加到DOM对象的方式。
