Shortcode is not working

Shortcode is not working in Sribe. I am using Caldera Forms plugins shortcodes. I have checked the shortcode in native WordPress editor that works fine, but when I add that in an Upfront text or widget element it does not work.
When I add in Upfront Text Element it just outputs the shortcode. 
And when I added in Custom HTML Widget the button is showing, but that does not work. The shortcode button should popup a modal.
