使用CK-Editor将光标指针移动到第一个位置onclick textarea

Question

我正在使用CK-Editor 4。我在其中创建了指令。当我点击Textarea时，我的光标指针是Move to First position。当我点击Textarea中的任何一个地方时，我希望我的光标位置可用。在点击最后一个位置之前，它不能移动到第一个或最后一个位置。

vpb.directive('ckeInline', function ($timeout, $parse, $rootScope,$) {
return {
require: "ngModel",
link: function (scope, element, attrs, ngModel) {
  if (attrs.ckeInlineShowtitle) ngModel = "";
  isMobile = $(".ipad, .ipod, .android").length > 0;

  var destroy_this_editor = function(id)
  {

      setTimeout(function () {
        try{
            CKEDITOR.instances[id].destroy(true);
        } catch (ex) {
        }
      },500)

  }

  if (!isMobile) {
      var create_and_focus = function () {
          if (scope.setup.edit_mode || attrs.ckeNonEditMode) {
              attrs.$set('contenteditable', true);
              var a_id = attrs.ckeInlineId;
              var menu_selector = attrs.ckeInlineMenu;
              //get editor
              //create editor if doesn't exist
              var e = CKEDITOR.instances[a_id];
              if (!e) {
                  element.menu = $(menu_selector);
                  //set up behavior for menu
                  uif.wire_up_menu(element, scope);
                  //hide all menu bars
                  $("nav.text-editor-menu-bar").hide();
