kingthemes on "[Plugin: King Composer - Page Builder by King-Theme] Textarea don't work"

Hi there,

Using the textarea_html doesn't work. When I enter text and save it it doesn't save the data, do you know what I did wrong?

global $kc;
$kc->add_map( array( 'cs_text' => array( 'name' => __('Text', 'cs'), 'description' => __('Add a simpel textarea', 'cs'), 'icon' => 'fa-align-left', 'category' => 'Content', 'params' => array( array( 'name' => 'content', 'type' => 'textarea_html', ) ) ) )
);
add_shortcode('cs_text', 'cs_text');
function cs_text($atts) { retu $atts['content'];
}

Kind regards,
Yanick
