Revert option is not working

The revert option is not working as expected,

My ember Code is:

Admin.Inspector.extend()
    .named("Admin.RoleInspect.Inspector")
    .reopen({
        name: "AdminUser",
        icon: 'admin',
        logical: function () {
            return Admin.Role.detectInstance(this.get('model'));
        }.property('model'),
        titleView: Core.view.Message.extend()
            .reopen({
                tagName: 'h2',
                key: 'admin/role-inspect/details/title'
            }),
        bodyView: Admin.RoleDetailsView.extend()
            .named("Admin.RoleInspect.InspectorView")
            .reopen({
                roleModelBinding: 'inspector.model',
                readOnly: function () {
                    return !this.get('roleModel.canModify');
                }.property('roleModel.canModify'),
                hasChangesChanged: function () {
                    if (!Admin.RoleInspect.Inspector.detectInstance(this.get('inspector'))) { return; }
                    this.get('inspector').set('hasChanges', this.get('hasChanges'));
                }.on('init').observes('hasChanges'),
                roleModelCopyChanged: function () {
                    this.set('inspector.roleModelCopy', this.get('roleModelCopy'));
                }.observes('roleModelCopy')
            }),
        actionsView: Inspect.EditableModelFooter,
        save: function () {

                data: {
                    name: roleName,
                    description: roleDescription
                }
            }).done(function (result) {
                Core.notify({
                    title: 'Success',
                    message: 'Role Details Updated'

                Core.Error.show(reason || status);
            });
        },

                        this.get('inspector').save();
                        return false;
                    }
                }),

Inspect.registerInspector(Admin.RoleInspect.Inspector);

In my ember file, the save option is working fine. But the revert option not working as expect in my side. I need to revert the saved text and misspelling text while doing this operation. I'm new to the ember. I'm using ember-1.4.0. Thanks in advance. Your help will be appreciate.
