Newbie Help with state

I am very new to Ionic and AngularJS so please forgive me if this is stupid.
Please see code here

I am trying to have a tabbed view and inside one of the tab (Home) I have a button linked to ‘#/facts’ and in the state I have
.state(‘facts’, {
url: “/facts”,
templateUrl: “templates/facts.html”

})

I want this page to open outside of the tabs so I have assigned the templateUrl in the state definition. But when I click the button it takes me to the Contact tab instead of opening the facts.html and I cannot understand why
