Only void function can be called with the "new" keyword

I'm trying to use the Foundation's Reveal plugin in my Typescript code in following way (altered for readability):

var popup = new Foundation.Reveal($('#element'));

and I'm getting following error during compilation (in the end it does compile and work anyway):

TS2350: Only a void function can be called with the 'new' keyword.

How should I write it then?
