AngularJS + post the entire $scope for Controller in ASP.NET MVC

guys. I'm trying to call some AJAX Post trhu AngularJS, and I want to send all properties from my $scope variable. I have this form:

<div ng-controller="DiscountPrintsCtrl">

    <div>
    Choose the year:
    <select ng-model="selectedYear" ng-change="searchCourses()">
        <option ng-repeat="year in years" value="{{year.ID}}">{{year.Name}}</option>
    </select>
</div>

<div>
    Choose the course:
    <select ng-model="selectedCourse" ng-change="searchStudents()">
        <option ng-repeat="course in courses" value="{{course.ID}}">{{course.Nome}}</option>
    </select>
</div>

<div>
    Choose the student:
    <select ng-model="selectedStudent" ng-change="searchStudentDetails()">
        <option ng-repeat="student in students" value="{{student.ID}}">{{student.Name}}</option>
    </select>
</div>

<div ng-model="studentDetails">
    Details about the student:<br /><br />
    <label>Name: {{studentDetails.Name}}</label><br />
    <label>Number: {{studentDetails.Number}}</label><br />
    <label>Print quote: {{studentDetails.PrintQuote}}</label><br />
</div>

<div>
    <table>
        <thead><tr>
            <td></td>
            <td>Title</td>
            <td>Grade</td>
            <td>Summary</td>
            <td>Author</td>
            <td>Number of pages</td>
        </tr></thead>
        <tbody>
            <tr ng-repeat="publication in publications">
                <td><input type="checkbox" ng-model="publication.Selected" /></td>
                <td>{{publication.Title}}</td>
                <td>{{publication.Grade}}</td>
                <td>{{publication.Comments}}</td>
                <td>{{publication.Author}}</td>
                <td>{{publication.NumberOfPages}}</td>
            </tr>
        </tbody>
    </table>
</div>

<button ng-click="submitForm()" value="Confirm discounts" />

And I have this JS:

<script type="text/javascript">

function DiscountPrintsCtrl($scope, $http) {


    $http.get(url).success(function (years) {

        $scope.years = years;
        $scope.selectedYear = '';

    });

    $scope.searchCourses = function() {

        var url = '/json/GetCoursesFromYear?' + 
            'selectedYear=' + $scope.selectedYear;
        $http.get(url).success(function (courses) {
            $scope.course = courses;
            $scope.selectedCourse= '';
        });
    }

    $scope.searchAlunosAnoSemestre = function() {

        var url = '/json/GetStudentsFromCouse?' +
            'selectedCourse=' + $scope.selectedCourse;

        $http.get(url).success(function(students) {
            $scope.students = students;
            $scope.selectedStudent = '';
        });
    }

    $scope.searchStudentDetails = function() {

        var url = '';

        url = '/json/GetStudentDetails?' +
            'selectedStudent=' + $scope.selectedStudent;

        $http.get(url).success(function(studentDetails) {
            $scope.studentDetails= studentDetails;
        });

        url = '/json/GetPublicationsForStudent?' +
            'selectedStudent=' + $scope.selectedStudent;
        $http.get(url).success(function(publications) {
            $scope.publications = publications;
        });
    }

    $scope.submitForm = function () {
        // How to submit the entire $scope???
    }
}

Any idea? Any considerations about my JS code?? Thanks all!!!
