Angularjs ngDisabled comparison expression is not correct

I am trying to enable or disable a button in an angularjs application based on whether comparing two text fields with true or false. I gave an example of the code below, and also made it available in the plunter here http://plnkr.co/edit/rzly8hy21048YGzsx2gW?p=preview

As you can see, when you enter a string according to the saved string, the expression evaluates correctly, but the button never becomes available.

Any help would be appreciated.

Here is the HTML

    <!DOCTYPE html>
<html ng-app="plunker">

  <head>
    <meta charset="utf-8" />
    <title>AngularJS Plunker</title>
    <script>document.write('<base href="' + document.location + '" />');</script>
    <link rel="stylesheet" href="style.css" />
    <script data-require="angular.js@1.2.x" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.16/angular.min.js" data-semver="1.2.16"></script>
    <script src="app.js"></script>
  </head>

  <body ng-controller="MainCtrl">
    <button ng-click="updateCounter()">Increment count</button>
    <input type="text" ng-model="inputfield">
    <input type="button" value="Continue" ng-disabled="{{inputfield !== startertext}}">
    <br>startertext: {{startertext}}
    <br>nputfield: {{inputfield}}
    <br>test: {{inputfield !== startertext}}

  </body>


</html>

And the Javascript file below.

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope) {
  $scope.startertext = 'hello world';
});
