Toggle checkbox on Twitter Bootstrap

I made a group of checkboxes with Twitter Bootstrap. Now I would like to do a "select all" or "deselect all" button. How could I do this using a JS function?

The Twitter Bootstrap documentation says to use $().button('toggle') but it doesn't work.

Here is my code snippet:

<div class="control-group">
<div class="controls">
    <div class="input">
        <div class="btn-group">
            <label class="btn  btn-toggle" for="colors-1-toggle-0">
                <input type="checkbox" id="colors-1-toggle-0" name="colors-1[]" value="color_c" />C
            </label>
            <label class="btn  btn-toggle" for="colors-1-toggle-1">
                <input type="checkbox" id="colors-1-toggle-1" name="colors-1[]" value="color_m" />M
            </label>
            <label class="btn  btn-toggle" for="colors-1-toggle-2">
                <input type="checkbox" id="colors-1-toggle-2" name="colors-1[]" value="color_y" />Y
            </label>
            <label class="btn  btn-toggle" for="colors-1-toggle-3">
                <input type="checkbox" id="colors-1-toggle-3" name="colors-1[]" value="color_k" />K
            </label>
        </div>
    </div>
</div></div>
