My program has a tab that opens a webview window which pulls information from a web server so that I can hopefully update the content and it will show up updated when I click on the tab again or switch back to the application in ios4. In the app.js page I have put the code:

tab1.addEventListener ('foucs', function(e){(webview.reload)});

Is there different code that I should be using to refresh the tab or get the whole application to refresh when switched back to.
