Modal to edit Angularjs and Laravel

I'm trying to make a Modal to edit my data, using AngularJS and laravel as backend, but when I call a function in my ng-submit (), it is not invoked.

This is my modal

    <div class="modal fade" id="mymodal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel">Modal title</h5>
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">
        <form ng-submit="salvar()">
            total:<input type="" ng-model="editar.total"  name="total">
            total:<input type="" ng-model="editar.quantidade_produtos"  name="quantidade_produtos">
                  <div class="modal-footer">
                    <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
                    <button type="button" type="submit" class="btn btn-primary">Save changes</button>
                </div>
        </form>
      </div>
    </div>
  </div>
</div>

And this is my code angularjs

   var app = angular.module('myApp', []);

app.controller('myCtrl', function($scope, $http) {

    $scope.editar = function(data){
        $scope.modal = data;
        $('#mymodal').modal('show');
    }

    $scope.salvar = function(){
        $scope.editar = {}
        $scope.d = $scope.modal.id;
        console.log($scope.editar); 

    }
    )};
