ionic/angular leaflet directive - zoom in/out buttons do not work

I have some problems with default zoom in/out buttons on leaflet map. Everything works fine when I load page directly but when I change one state to state where leaflet directive is buttons just do not work. Here you go example

The code:

HTML

<html ng-app="app">
<head>
<meta charset="utf-8"/>
<meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width"/>
<link href="http://code.ionicframework.com/1.0.0-beta.11/css/ionic.min.css" rel="stylesheet"/>
<link rel="stylesheet" href="http://cdn.leafletjs.com/leaflet-0.7.3/leaflet.css" />
<title>Leaflet example</title>
</head>
<body>
<ion-nav-view></ion-nav-view>

<script type="text/ng-template" id="locations.html">
<ion-view title="Locations">
<ion-content>
<ion-list can-swipe="true">
<ion-item ng-click="locationOnClick(location)" class="item item-icon-left" ng-repeat="location in locations">
<i class="icon ion-location"></i>
<h2>{{location.name}}</h2>
</ion-item>
</ion-list>
</ion-content>
</ion-view>
</script>
<script type="text/ng-template" id="location.html">
<ion-view title="{{location.name}}">
<ion-nav-bar class="bar-positive" animation="nav-title-slide-ios7">
<a ui-sref="locations" class="button icon-left ion-chevron-left button-clear ">Locations</a>
</ion-nav-bar>
<ion-content>
<leaflet height="480px"></leaflet>
</ion-content>
</ion-view>
</script>
<script src="http://cdn.leafletjs.com/leaflet-0.7.3/leaflet.js"></script>
<script src="http://code.ionicframework.com/1.0.0-beta.11/js/ionic.bundle.min.js"></script>
<script src="http://tombatossals.github.io/angular-leaflet-directive/dist/angular-leaflet-directive.min.js"></script>
</body>
</html>


JS

angular.module('app', [
'ionic',
'leaflet-directive'
])
.config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('locations', {
url: "/locations",
templateUrl:"locations.html",
controller: 'LocationsCtrl'
})
.state('location', {
url: "/location/:locationId",
templateUrl: "location.html",
controller: 'LocationCtrl'
});


// if none of the above states are matched, use this as the fallback
$urlRouterProvider.otherwise('/locations');

})
.factory('locationService', function(){
var _locations = [{
id: 1,
name: 'Sample location',
lat: 50,
lng: 50
}];
return {
getAll: function(){
return _locations;
},
getById: function(id){
return _locations.filter(function(loc){ return loc.id === id; })[0];
}
}
})
.controller('LocationsCtrl', function($scope, $location, locationService){
$scope.locations = locationService.getAll();

$scope.locationOnClick = function(location){
$location.path('/location/'+location.id);
};
})
.controller('LocationCtrl', function($scope, $stateParams, locationService){
$scope.location = locationService.getById($stateParams.locationId);
})

Answer

The solution was simple. Ionic was "eating" all click events which was not created by a framework. For the container of leaflet map there was a need to add attribute data-tap-disabled="true"

<ion-content data-tap-disabled="true">
    <leaflet height="480px"></leaflet>
</ion-content>
