Refresh extension page in a new tab

[sankarkumar23]

In background.js I have the below code. Note: I do not have popup.html page in my extension
chrome.action.onClicked.addListener(function(activeTab)
{
var newURL = "index.html";
chrome.tabs.create({ url: newURL });
});

When I click on the extension icon the page is loading up correctly in new tab. This page is not reloading automatically with code change.. I am forced to refresh.
chrome-extension:///index.html
Is there any trick to get this page also refreshed automatically?
