Answer 1

Use

  <button class="btn btn-default" type="button" id="homebtn" ng-click="navigate ('home')">Home</button>  

and in controller,

$scope.navigate = function(routeName){
  $state.go(routeName)
};

Answer 2

I noticed you have written

ngController="contactController"

It should be

<div ng-controller="contactController">

After that change your contactController as following. Put it after module initialization.

app.controller('contactController', ['$scope', '$state', function ($scope, $state) {
        $scope.home = function () {
            $state.go('home');
        };
    }]);

Answer 3

I finally got it working.

    function contactController($scope, $state) {
  $scope.navigate = function(home){
    $state.go(home)
  };

};

I was missing $scope as a parameter inside my controller function.
