jQuery remove(selector) doesn't seem to work

Question

I created a small jsfiddle: http://jsfiddle.net/duRXc/

<div data-role="wrapper">
    <span class="to-be-removed" data-role="to-be-removed">
        text to be removed
    </span>
</div>
<button id="remove1">Remove by jQuery object</button><br>
<button id="remove2">Remove by selector</button><br>
<button id="remove3">Remove by selector(class)</button>

var $wrapper = $('[data-role="wrapper"]');

$('#remove1').on('click', function () {
    $wrapper.find('[data-role="to-be-removed"]').remove();
});

// this should work: http://api.jquery.com/remove/
$('#remove2').on('click', function () {
    $wrapper.remove('[data-role="to-be-removed"]');
});

// this should work: http://api.jquery.com/remove/
$('#remove3').on('click', function () {
    $wrapper.remove('.to-be-removed');
});

The problem I'm having is that the .remove(selector) overload is not working. I thought it had something to do with my data-role selector, but the remove by class selector doesn't work as well.

Am I doing something wrong? Or is this a bug in jQuery or maybe the docs are wrong:

We can also include a selector as an optional parameter

Answer 1

$wrapper.find('span').remove('[data-role="to-be-removed"]')

is the same as

$wrapper.find('span').filter('[data-role="to-be-removed"]').remove()

var $wrapper = $('[data-role="wrapper"]');

$('#remove1').on('click', function () {
    $wrapper.find('[data-role="to-be-removed"]').remove();
});

// this should work: http://api.jquery.com/remove/
$('#remove2').on('click', function () {
    $wrapper.find('[data-role="to-be-removed"]').remove('[data-role="to-be-removed"]');
});

// this should work: http://api.jquery.com/remove/
$('#remove3').on('click', function () {
    $wrapper.find('[data-role="to-be-removed"]').remove('.to-be-removed');
});
