Google maps marker isn't draggable in ionic application

Hi guys!

I have a problem. I create ionic application and include google maps to it. It works fine but it is one problem. When I set to marker draggable property to true marker doesn’t drag. When I do the same work on blank html page only with google maps and without anything frameworks it works fine. What can be wrong?

It’s my html:

<ion-view view-title="Maps">
     <div id="map" data-tap-disabled="false"></div>


  height: 100%

  width: 100%
  height: 100%

My controller:

angular.module ('myApp.controllers')
  .controller ('MapsCtrl', function ($scope) {

var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
var mapOptions = {
  zoom: 4,
  center: myLatlng
var map = new google.maps.Map(document.getElementById("map"), mapOptions);

var marker = new google.maps.Marker({
  position: myLatlng,
  map: map,
  title:"Drag me!"

$ = map;
