Failed to call asset() when use container with queue

[Cengkaruk]

Hi Teepluss,

I got this error when try to use queue group (also single queue).

$theme->asset()->queue('compress-footer', function($asset)
{
    $theme->asset()->container('footer')->usePath()->add('bootstrap', 'js/bootstrap.min.js', array('core-script'));
    $theme->asset()->container('footer')->usePath()->add('wow', 'js/wow.min.js', array('core-script'));
});

Call to a member function asset() on a non-object

Thanks

$theme->asset()->queue('compress-footer', function($asset)
{
    $asset()->container('footer')->usePath()->add('bootstrap', 'js/bootstrap.min.js', array('core-script'));
    $asset()->container('footer')->usePath()->add('wow', 'js/wow.min.js', array('core-script'));
});
