Uncaught ReferenceError: Invalid left-hand side in assignment

I'm getting this error and the todos wont render. The error points to line 30 in main.js

dataService.saveTodos(ng-model="todo.name");

Here is the entire main.js file:

'use strict';

angular.module('todoListApp')
.controller('mainCtrl', function($scope, dataService) {
  $scope.todos = []; //added this line
  $scope.addTodo = function() {
    var todo = {name: "This is a new todo."};
    $scope.todos.push(todo);
  };

  $scope.learningNgChange = function() {
    console.log("An input has changed");
  };

  dataService.getTodos(function(response) {
    console.log(response.data);
    $scope.todos = response.data;
  });

  $scope.deleteTodo = function(todo, $index) {
    dataService.deleteTodo(todo);
    $scope.todos.splice($index, 1);
  };

  $scope.saveTodos = function(todo) {
    var filteredTodos = $scope.todos.filter(function(todo) {
      if(todo.edited) {
        return todo;
      };
    })
    dataService.saveTodos(ng-model="todo.name");
  };

})

Here is my todos.js file:

angular.module('todoListApp') 
.directive('todos', function() {
  return {
   templateUrl: 'templates/todos.html',
   controller: 'mainCtrl',
   replace: true
  }
})

And my todos.html file:

  <div class="list">
      <div class="add">
    <a href="" ng-click="addTodo()">+ Add a new task</a></div>    
      <div class="item" ng-class="{'editing-item': editing, 'edited': todo.edited}" ng-repeat="todo in todos">
       <input ng-model="todo.completed" type="checkbox" />
        <span ng-click="todo.completed = !todo.completed; todo.edited = true"></span>
      <label ng-hide="editing" ng-click="helloWorld()">{{todo.name}}</label>
      <input ng-change="todo.edited = true" ng-blur="editing = false;" ng-show="editing" ng-model="todo.name" class="editing-label" type="text"> 
      <div class="actions">
        <a href="" ng-click=" editing = !editing">edit</a>
        <a href="" ng-click="saveTodos(todo)">save</a>
        <a href="" ng-click="deleteTodo(todo, $index)" class="Delete">delete</a>
      </div>
    </div>
  </div>

And finally my index.html file:

<!doctype html>
<html lang="en">
<head>
  <title></title>
  <link href='https://fonts.googleapis.com/css?family=Varela+Round' rel='stylesheet' type='text/css'>
  <link href='styles/main.css' rel='stylesheet' type="text/css">
</head>
<body ng-app="todoListApp">
  <h1 ng-click="helloWorld()"> My TODOs</h1>
<todos></todos>

  <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular.min.js"></script>
  <script src="scripts/app.js" type="text/javascript"></script>
  <script src="scripts/controllers/main.js" type="text/javascript"></script>
  <script src="scripts/services/data.js" type="text/javascript"></script>
  <script src="scripts/directives/todos.js" type="text/javascript"></script>
</body>
</html>

Any suggestions for my code?

Thanks :)

:point_right: It looks like you mixed in some stray HTML code as your argument.

The final workspace code has that line written this way:

    dataService.saveTodos(filteredTodos);
