angularjs - Change background colour of button when clicked

I would like to change the background colour of a button when it is clicked

HTML code:

<div class="btn-group">
    <button type="button" class="btn btn-default" ng-click="style1()">
        Celsius
    </button>
     <button type="button" class="btn btn-default" ng-click="style2()">
        Fahrenheit
    </button>
</div>

Angular code where the background colours of the buttons should be changed:

$scope.style
 {
 };
$scope.style2
 {
 }

You should do it this way

angular.module('myapp',[]).controller('testCtrl', function($scope){});

<html ng-app="myapp">

<head>
  <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
</head>

<body ng-controller="testCtrl">
  <div class="btn-group" ng-init="style={'background-color' : 'green'}">
    <button type="button" class="btn btn-default" ng-style="style1"
            ng-click="style1=style; style2=null">Celsius</button>
    <button type="button" class="btn btn-default" ng-style="style2"
            ng-click="style2=style; style1=null">Fahrenheit</button>
  </div>
  <br>
</body>

</html>
