Ion-item with checkbox and icon on item-icon-right & icons in ion-option

ionic-v1
3

Hello, Thank you for your help.

The first icon ion-ios7-arrow-left is OK
Unfortunately the second one : ion-close-round is not displayed in the options.

Without the ion-ios7-arrow-left - I love Kittens display properly the ion-close-round.

        <ion-item>
      <div class="item-checkbox">
       <label class="checkbox">
         <input type="checkbox"  
         ng-model="groupe0.checked" 
         ng-checked="groupe0.checked"
         ng-change="">
       </label>
       <span>I love kittens!</span>
      </div>
      <ion-option-button class="button-positive">Share</ion-option-button>
      <ion-option-button class="button-assertive icon ion-close-round"></ion-option-button>
      <ion-option-button class="button-positive">Edit</ion-option-button>
    </ion-item>

    <ion-item class="item-icon-right">
      <div class="item-checkbox">
       <label class="checkbox">
         <input type="checkbox"  
         ng-model="groupe1.checked" 
         ng-checked="groupe1.checked"
         ng-change="">
       </label>
       <span>I love Dogs</span>
      </div>
      <i class="icon ion-ios7-arrow-left"></i> 
      <ion-option-button class="button-positive">Share</ion-option-button>
      <ion-option-button class="button-assertive icon ion-close-round"></ion-option-button>
      <ion-option-button class="button-positive">Edit</ion-option-button>
    </ion-item>
