I have used 2 button in the form. I want to disable button1 on initialisation though I have given ng-disabled="true" but whenever user clicks on button2, button1 get enabled. Can anyone tell me how to do this in angularjs ?

You don't need to do anything in the controller if you are not working with the scope variable inside the controller.
So just do something like:
angular.module("app",[]).controller("ctrl",function($scope){})<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
<button ng-disabled="first !== true"> one</button>
<button ng-click="first = true"> two</button>
</div>Comments
You can call one function on click of second button and set the ng-disabled value to false.
DEMO
var myApp = angular.module('myApp',[]);
myApp.controller('MyCtrl',function($scope) {
$scope.inactive= true;
$scope.enableButton1 = function() {
$scope.inactive= false;
}
});<div ng-app="myApp" ng-controller="MyCtrl">
<br><input type="button" ng-disabled="inactive" value="button1"/>
<br><input type="button" ng-click="enableButton1()" value="button2"/>
</div>

use scope variables and assign them to ng-disabled
angular.module("app",[])
.controller("ctrl",function($scope){
$scope.firstBtn = true;
$scope.secondBtn = false;
})<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
<button ng-disabled="firstBtn" > one</button>
<button ng-disabled="secondBtn" ng-click="firstBtn = false"> two</button>
</div>

Its very simple as given below:
JS
var app = angular.module('myApp', []);
app.controller('ctrl', function($scope) {
$scope.isDisabled = true;
$scope.toggleButton = function() {
$scope.isDisabled = !$scope.isDisabled;
}
});
HTML
<div ng-app='myApp'>
<div ng-controller='ctrl'>
<button ng-click='toggleButton()'>
Toggle
</button>
<button ng-disabled='isDisabled'>
I am button
</button>
</div>
</div>
