ngInit

  1. - directive in module ng

The ngInit directive allows you to evaluate an expression in the current scope.

The only appropriate use of ngInit is for aliasing special properties of ngRepeat, as seen in the demo below. Besides this case, you should use controllers rather than ngInit to initialize values on a scope.
Note: If you have assignment in ngInit along with $filter, make sure you have parenthesis for correct precedence:
<div ng-init="test1 = (data | orderBy:'name')"></div>

    }]);
</script>
<div ng-controller="ExampleController">
  <div ng-repeat="innerList in list" ng-init="outerIndex = $index">
    <div ng-repeat="value in innerList" ng-init="innerIndex = $index">
       <span class="example-init">list[ {{outerIndex}} ][ {{innerIndex}} ] = {{value}};</span>
    </div>
  </div>
</div>
it('should alias index positions', function() {
  var elements = element.all(by.css('.example-init'));
  expect(elements.get(0).getText()).toBe('list[ 0 ][ 0 ] = a;');
  expect(elements.get(1).getText()).toBe('list[ 0 ][ 1 ] = b;');
  expect(elements.get(2).getText()).toBe('list[ 1 ][ 0 ] = c;');
  expect(elements.get(3).getText()).toBe('list[ 1 ][ 1 ] = d;');
});
