[Trinidad] Trigger onchange on keyup ?

[Michael Borchert]

Hi all, 

I try to have a table populated on the immediately (with a small
timeout ) when an input field changes. 

I've done it this simple way below, it works but is not really what I
want. I want the onchange wto trigger if there was no key pressed for
xxx ms. 

As I'm not the javascript crack, has anyone implemented a solution for
that or does Trinidad provide another solution? 
                                                                        
<tr:inputText id="eingabe" label="Präparatename:"
value="#{productBean.name}" autoSubmit="true"
partialTriggers="searchCriteria"
onkeyup="setTimeout(this.onchange,800);" />

Thanks for help,
Michael
