Data edit - modal Bootstrap - angularjs

Question

I have a problem with editing data in the bootstrap modal.
The problem is that in the modal, only first record from the database is displayed.
Modal only displays the problem because it retrieves data from 1 record.
Could it show me something wrong with the code, that it only gets 1 record for me?
My code AngularJS:
controllersAdmin.controller('linkEdit', function( $scope, $http, $routeParams, $timeout){
var linkID = $routeParams.id;
$scope.id = linkID;
$scope.link = function( link ){
$http({
method: 'GET',
url: 'api/admin/links/get/' + linkID,
}).then(function (response){
$scope.link = response.data.records;
},function (error){
console.log('Blad we wczytywaniu danych');
});
}
$scope.saveChanges = function( link ){
$http({
method: 'POST', url: 'api/admin/links/update/', data: {'link' : link}},
).then(function (){
$scope.success = true;
},function (error){
console.log('Blad we wczytywaniu danych');
});
}
});
<tr ng-repeat="link in link">
<td>{{$index+1}}</td>
<td>{{link.links | limitTo:50}}...</td>
<td>{{ link.login }}</td>
<td>{{link.password}}</td>
<td>{{link.date}}</td>
<td>
<button ng-click="deleteLink(link, $index)" class="btn btn-danger">×</button>
