Iphopne checkbox plugin etc

Hi,

yesterday I've bought the plugin pack, how can I do to setDisabled the iphone plugin?
In my JavaOnload event there is this code to enable/disable the checkbox, but with the plugin don't works
var DISPO = Runner.getControl(pageid, 'Disponibile');

...

DISPO.setDisabled();
I've some other problem with other plugin, in Spinner, how can i check when user increase or decrease a number?

events on.click mouseup mousedown etc. don't works! <img src='https://asprunner.com/forums/file.php?topicimage=1&fieldname=question&id=21275&image=1&table=forumtopics' class='bbc_emoticon' alt=':(' /> <img src='https://asprunner.com/forums/file.php?topicimage=1&fieldname=question&id=21275&image=2&table=forumtopics' class='bbc_emoticon' alt=':(' /> <img src='https://asprunner.com/forums/file.php?topicimage=1&fieldname=question&id=21275&image=3&table=forumtopics' class='bbc_emoticon' alt=':(' />
