Filter between two dates in visual composer

Hi,

I am working in a dashboard with visual composer 7.2, I am triying to filter between two dates but i can´t do it. We only want two filelds, one for the initial date and the other is for the final date.

I have attached the url with a document where I explain this in detail.

any idea??
