Page Builder and code compatibility

I tried to use page builder and added some custom code for making a text area in that page. But it doesn’t seem to be compatible with any code, since when I tried the text area did not come on the page with active plugin page builder. But when I deactivated this plugin the area is visible now. Is it suppose to be like that or I am doing something incorrect? Or we are not suppose to use our own codes with this plugin? And also is the page builder compatible with jquery?

I used the following code:

<textarea rows=”5″ cols=”100″ id=”id”> </textarea>
