[angularjs] Pass a reference to DOM object with ng-click

I have multiple elements with the same callback on ng-click:

<button ng-click="doSomething()"></button>
<button ng-click="doSomething()"></button>
<button ng-click="doSomething()"></button>
<button ng-click="doSomething()"></button>

// In controller:
$scope.doSomething = function() {
  // How do I get a reference to the button that triggered the function?
};

How can I get the reference to the object which made the call to doSomething? (I need to remove an attr from it)

While you do the following, technically speaking:

<button ng-click="doSomething($event)"></button>

// In controller:
$scope.doSomething = function($event) {
  //reference to the button that triggered the function:
  $event.target
};

This is probably something you don't want to do as AngularJS philosophy is to focus on model manipulation and let AngularJS do the rendering (based on hints from the declarative UI). Manipulating DOM elements and attributes from a controller is a big no-no in AngularJS world.
