Does anyone having the same or related issues about it? This is a regular ion-list with regular option buttons. I am using Beta 13. Note that testing the same app in an Android 4.4.4 everything works fine. The image and the code are:
<ion-view title='{{resumeTitle()}}'>
<ion-header-bar align-title="center" class="bar-subheader positive-bg">
<a class="button button-icon icon ion-ios7-personadd button-positive" ng-click="modal.show()"></a>
<h1 class="title light">{{saleClient ? "Cliente: " + saleClient.name : "Escolha o cliente (opcional)"}}</h1>
<a class="button button-icon icon ion-ios7-close-empty button-positive" ng-click="unsetSaleClient()"></a>
</ion-header-bar>
<ion-content padding="false" has-bouncing="true" class="has-footer">
<ion-list>
<ion-item ng-repeat="resumeItem in resumeItens" class="item-energized" style="backgroud-color:#FFFF">
<h2>{{resumeItem.name}}</h2>
<p>R$ {{resumeItem.price}}</p>
<span class="badge badge-positive">{{resumeItem.qtd}}</span>
<ion-option-button ng-click="increaseQtd(resumeItem)"><i class="button-icon icon ion-chevron-up positive vertical-center"></i></ion-option-button>
<ion-option-button ng-click="decreaseQtd(resumeItem)"><i class="button-icon icon ion-chevron-down energized vertical-center"></i></ion-option-button>
<ion-option-button ng-click="remove_item(resumeItem)"><i class="button-icon icon ion-minus-circled assertive vertical-center"></i></ion-option-button>
</ion-item>
</ion-list>
</ion-content>
<button class="button button-large button-full button-positive hide-on-keyboard-open"
style="position: absolute;
bottom: 0px;
width: 100%;
margin-bottom: 0px;"
ng-click='showPaymentOpts()'>
<img src="icons/checkout_icon.svg" class="img-create-button">
Pagar
</button>
For the record, some parts in code are in portuguese, cuz I’m working from Brazil.
