ng-model no longer updates after typing into text input

I am new to AngularJS and I am having a problem that I am having trouble solving, there was a similar question on stackoverflow but it didn’t seem to help me out. I basically have a form that gets updated by ng-click, but once once I enter text into any of the text boxes, those text boxes no longer update.

This is my HTML

Edit Course:
<li ng-repeat="course in courses">
    <a ng-click="Edit_Course(course.id)">{{course.course_name}}</a>
<div ng-show="showedit == 1">
  <form novalidate ng-submit="edit_course()" class="simple-form">
    <label for="form_course_name">Course</label>
      <input type="text" id="form_course_name" ng-model="edit_course_name">
    <label for="form_par">Par</label>
      <input type="text" id="form_par" ng-model="edit_course_par">
    <label for="form_course_location">Course Location</label>
      <input type="text" id="form_course_location" ng-model="edit_course_location">
     <input type="submit" id="submit" value="Edit Course" />

This is my function that is called when someone clicks on a link

$scope.Edit_Course = function (id) {
    var course = {
        'course_id' : id

    $http({method: "POST", url: "http://www.dgcharts.com/editcourse", data: course})
    .success(function(data, status, headers, config){

      thecourse = data["course"];
      $scope.edit_course_name = thecourse.course_name;
      $scope.edit_course_par = thecourse.par;
      $scope.edit_course_location = thecourse.course_location;
      $scope.edit_course_id = thecourse.id;
      $scope.showedit = 1;

your link requires a login.

if i have to guess about your problem, it may be related to angular scoping issue. try changing your ng-model binding to an object property instead. so in your html, instead of:

<input type="text" id="form_course_name" ng-model="edit_course_name">

do this

<input type="text" id="form_course_name" ng-model="course.edit_course_name">

and in your javascript, on the ajax callback, change it to:

$scope.course = {};  //only do this if $scope.course has not already been declared
$scope.course.edit_course_name = thecourse.course_name;
