Because your JavaScript code will run on the client, which sees an
HTML DOM in the web browser. That DOM respresents the HTML document
produced by Orbeon Forms when it transforms XForms+XHTML into plain
HTML. That DOM does not include in XForms elements.
Remember, the Orbeon XForms implementation works server-side in order
to support current browsers. It achieves this by sending to web
browsers not XForms (which they wouldn't understand), but HTML,
JavaScript, and CSS (which they do understand).
Technically, it would not be impossible to support server-side
JavaScript DOM mutations, but we don't really see a strong use case
for this.
If you just want to conditionally include XForms controls, you can use
an XSLT page view. If you want to control appeareance of XForms
controls at runtime, you can use relevance or switch/case. Currently,
the only thing you can't do is dynamically add and remove trees of
controls in a given XForms page.
