select elements outsde of plugin chaining this keyword
<p>hi im creating a plugin with chaining the problem is I want to select elements outside of the THIS element e.g</p>

<pre><code>return $this.each(function() {
    $('body $left .filter-wrapper input[type=checkbox]', document).change(function() {
        alert('changed');// I want to break out side the scope how do i do that
        and select element that aren't in $('mygrid').Grid()
        // ive tried $('body $left .filter-wrapper input[type=checkbox]') 
        // that doesn't work either
    }).find(this).filter(....).click(function() {
        // this refers to mygrid which is what i want but the ubove code doen't work 
    }).find(....).click(function(){
        // do more stuff here
    }).bind('....')
});
</code></pre>
