It seems, you are generating wrong value of onChange attribute (which
cannot trigger a form submit).

I think, you need to do:
<xsl:attribute name="onChange">document.forms[0].submit()</xsl:attribute>
(if there is a single form in the page)

or,

<xsl:attribute name="onChange">document.formName.submit()</xsl:attribute>
(if you know the form by name)

Your problem does not seem at the XSLT level. It seems to be at the HTML level.
