How to refresh menu bar app on click?

[Tom Genoni]

I have a Fluid menu bar app that shows a list of bugs assigned to me. The problem is that I need to manually refresh it each time I look at it. I know I can do a setTimeout but I don't want to use that as it will make far too many wasted calls to the server and will occasionally refresh while I'm looking at it.

Is there a click event that's available for me to use in Userscripts that I could use to refresh the page I'm viewing? Something like:

$(window.fluid).click(function(){

 //reload page page

})
