Chrome WebNavigation Listener not working

I'm creating my own extension for Google Chrome (for my own use, not to be published). At the moment I have two files:

manifest.json:

{
  "manifest_version": 2,
  "name": "abcdef",
  "description": "abcdef",
  "version": "0.1",
  "permissions": [
    "tabs",
    "webNavigation",
    "http://www.ztm.waw.pl/*"
  ],
  "background": {
    "scripts": ["bg.js"],
    "persistent": false
  }
}

bg.js:

chrome.webNavigation.onCompleted.addListener(function(o) {
  chrome.tabs.executeScript(o.tabId, {
    code: "alert('ok');"
  });
}, {
  url: {
    hostContains: 'ztm.waw.pl'
  }
});

I want the alert box to appear when I navigate to http://www.ztm.waw.pl, but it does not work. Could someone tell me why?

The url property of chrome.webNavigation.onCompleted accepts an array of chrome.events.UrlFilter (source), so you'll need to change your bg.js to this (note the square and curly brackets in the url property):

chrome.webNavigation.onCompleted.addListener(function(o) {
  chrome.tabs.executeScript(o.tabId, {
    code: "alert('ok');"
  });
}, {
  url: [
    {hostContains: 'ztm.waw.pl'}
  ]
});
