How do I use an Xpages onchange event to activate a button

Question

I am trying to find how to make an onChange event for a check box initiate a button press for a button on the same page. I have had a search on google but can't find how this is done. Is such a thing possible in xpages?

EDIT: More information and code

My problem is the users run a search and want the option to omit cancelled records or include them. I tried for days to get the view to update just by clicking on a checkbox but it would only refresh after the user changed the check box value and clicked somewhere on the page. I tried partial refresh and complete refresh etc on the check box to refresh the dynamicviewpanel etc. I tried using viewScope variables to determine the check box value but nothing worked. I found it worked if I included a button to do a complete refresh and I thought I could hide the button and have the check box click the button. I have tried adding Knut's suggestion below but it still only works when I click also the button or somewhere else on the page.

This is an example for automatically clicking a button on checkbox' onchange event:

<?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="http://www.ibm.com/xsp/core">
    <xp:checkBox
        text="check it"
        id="checkBox1"
        value="#{viewScope.test}">
        <xp:eventHandler
            event="onchange"
            submit="false">
            <xp:this.script><![CDATA[
                document.getElementById('#{id:button1}').click()
            ]]></xp:this.script>
        </xp:eventHandler>
    </xp:checkBox>
    <br />
    <xp:button
        value="Label"
        id="button1">
    <xp:eventHandler
        event="onclick"
        submit="false">
        <xp:this.script><![CDATA[alert("hi")]]></xp:this.script>
    </xp:eventHandler></xp:button>
</xp:view>
