Close popup with jQuery

I’ve created a popup with a button. The button scrolls to a specific anchor on my page. This is done by action = Go to url and the URL = http://www.website.com/#anchor

This seems to work perfectly. But after you click on the button, I want the popup to close.
So I thought that I could trigger a click on the close icon.

jQuery('#lp-pom-button-19').on('click', function(){
    jQuery('.ub-emb-close').trigger('click');
    console.log('test');

});

But that doesn’t seems to work, only the “test” is printed in the console screen.
How can I close the popup after the scroll?

Thanks
