ng-show, toggle right element on click [Angularjs]

I wana toggle elements but not all elements i need just one on which is clicked.

for example if I have 3 form elements and 3 buttons if I click on button 1. I just wana toggle 1. form element.

This is my current code:

angular:

$scope.formWhat = false;
$scope.formShow = function(item){
                   $scope.formWhat = !$scope.formWhat;
               };

html:

<div ng-repeat="x in comments">
<a href="#" ng-click="formShow(x)">replay</a>
       <form id="<%x.id%>" ng-show="formWhat">
        blbllblblbl
        </form>
</div>

This code will open all forms, but i need just on which is clicked, any idea?
