It works now...
I GET array and stick name in input, then I change name in input and PUT it.
HTML
<form id="edit">
    <table>
        <tr>
            <th>Name: </th>
            <td>
                <input id="name" form="edit" type="text" ng-model="name" required>
            </td>
        </tr>
    </table>
    <button ng-click="edit()">Submit</button>
</form>
AngularJS
$scope.display = function()
{
    var connection = $http(
    {
        method: 'GET',
        url: 'http://localhost:8080/students?id=' + $scope.id
    })
    .then(function(response)
    {
        $scope.myArray = response.data;
        $scope.name = $scope.myArray[0].name;
    })
