Hi, I would like to know how I can attach and event or what I need to modify in order to attach another function to the Sencha Grid when 'update' is clicked. With this, I mean this button:


I realize Sencha attached a function that updates the store on the client side, but if say, I wanted to do an XMLHTTPREQUEST or simply change a button's look when this is clicked, how could I do that? Since Sencha seems to generate that button on the fly, I can't use document.getElementsByTagName or the like.
