How to make Angular Translate js working with Search Filter when language changed?

I’m not able to make Angular Translate working with Search Filter . When the language is English the list items are searchable. But when the language is bangla the items are still searchable in english but not in bangla. Is there any solution?

                  <label class="item item-input">
                    <i class="icon ion-search placeholder-icon"></i>
                    <input type="text" ng-model="input.filterUser" placeholder="Search">
                  <ion-item class="item-avatar" ng-repeat="user in groups | filter:input.filterUser">
                    <img src="{{user.avatar}}">           
                    <h2>{{ | translate}}</h2>
