How to add element to the desired div using js?

Hi all, client has shareware theme for wordpress customify. The theme allows internal forces WP to customize the header and footer, and has a limited number of items for customization. 1 Logo, 1 menu, and 1 field of arbitrary insertion and so on.

The client needed to make a top hat is another set with the text of the city, but buying for the sake of the Pro version of the theme for 50$ I do not see sense. The markup below, the second p element I've added for example. How to add in the right div is created by the Builder single text element using js?

<div class="builder-header-html-item item html--">
 <p>Production pools of polipropilene</p> ---------> // arbitrary unit themes embedded in the theme
 <p>Moscow</p> ---------> // the item you want to add.
</div>

Solution
For example, using innerHTML.
Either insert the second text in the first block, time it anything can be inserted.
