Weird keyboard behaviour

Hi guys.

I made a video for this.

Here’s the view

It only happens on android devices (This is a 5.x one)

<ion-view class="chat-view">
    <ion-nav-title>
        {{schedule.name || "Carregando.."}}
    </ion-nav-title>
    <ion-nav-buttons side="right">
        <button class="button button-clear ion-information-circled" ng-click="openPopover($event)"></button>
    </ion-nav-buttons>
    <ion-content has-bouncing="true" class="padding" delegate-handle="chat-scroll">
        <ion-refresher pulling-text="Carregando mais mensagens.." on-refresh="loadBefore()"></ion-refresher>
        <ion-list>
            <div class="item-text-wrap" ng-class="{
                'chat-message': message.user.id != user.id,
                'chat-message-self': message.user.id == user.id,
                'same-last-user': message.user.id == messages[$index - 1].user.id,
                'pending': message.id == undefined
            }" ng-repeat="message in messages">
                <div class="avatar">
                    <img ng-click='viewUser(message.user)' handle-load-error class="profile-image" src="img/placeholder.jpg" ng-src="{{message.user.image_url}}" alt="foto perfil do usuario">
                </div>
                <div on-hold='messageOptions(message)' ng-class="{
                    'chat-bubble': message.user.id != user.id,
                    'chat-bubble-self': message.user.id == user.id
                }">
                    <h2 class="c-username" ng-style="{
                        'color': getUserColor(message.user.id)
                    }">
                        <span class="username">{{::message.user.username}}</span>
                        <span class="timestamp" am-time-ago="message.created_at"></span>
                    </h2>
                    <p compile="::message.content | smartchat"></p>
                </div>
                <div class="like-button" ng-click='toggleLike(message)'>
                    <i class="icon" ng-class='{
                        "ion-ios-heart-outline": !message.liked,
                        "ion-ios-heart": message.liked
                    }'></i>
                    <p class="counter-like">{{message.count_likes}}</p>
                </div>
            </div>
            <div class="clearfix"></div>
        </ion-list>
    </ion-content>
    <ion-footer-bar class="bar-stable item-input-inset message-footer" keyboard-attach>
        <label class="item-input-wrapper">
            <textarea placeholder="Digite sua mensagem.." ng-model="currentMessage" minlength="1" maxlength="1500" msd-elastic ng-focus="inputUp()" ng-blur="inputDown()"></textarea>
        </label>
        <div class="footer-btn-wrap">
            <button class="button button-icon icon ion-android-send footer-btn" type="submit" ng-click="submitMessage(currentMessage)" ng-class="{
            disabled: !currentMessage || currentMessage.trim().length == 0
        }">
            </button>
        </div>
    </ion-footer-bar>
</ion-view>

Heres the controller for those actions

$scope.inputUp = function() {
            if (isIOS) {
                $scope.data.keyboardHeight = 216;
            }

            $timeout(function() {
                $ionicScrollDelegate.$getByHandle('chat-scroll').scrollBottom(true);
            }, 500);

        };

        $scope.inputDown = function() {
            if (isIOS) {
                $scope.data.keyboardHeight = 0;
            }
            $timeout(function() {
                $ionicScrollDelegate.$getByHandle('chat-scroll').resize();
            }, 500);
        };

This is happening only with crosswalk. Without crosswalk this does not happen

I found out that this is only happening on crosswalk and with android 5.
