First you need to add an app and a controller where you will implement your logic.

The aplication logic goes in the controllers. Aviod putting it in the templates.

Example:

template

<div ng-app="myApp">
<div ng-controller="MyCtrl">
 <button ng-click="btn_save()">Save</button>
 <button ng-click="btn_update()">update</button>
</div>

controller

var myApp = angular.module('myApp',[]);
function MyCtrl($scope) {
    $scope.btn_save = function(){
        alert("Button save clicked!")
    }
}

Is here, in the controller where you will implement the btn_save logic. In this case, the function throw an alert dialog when user clicks on button.
