HTML Checkbox - allow to check mutliple checkboxes

I have html code, which displays content in grid format, that is a row with three columns each, and each input field would be able to check. However, i am not able to check multiple checkboxes with below code. Whatever checkbox i choose, only the first box in the list is triggered and checked. Others remain ng-prestine. What would be the issue with my code

<table>
                <tr ng-repeat="(key, allergyList) in  filteredAllergies track by $index">
                    <td ng-repeat="allergy in allergyList track by $index">
                        <div class="ice-form-checkbox">
                            <input id="condition" ng-model="selectedAllergy" type="checkbox"/><label for="condition"><span>{{allergy.allergyName}}</span></label>
                        </div>
                    </td>
                </tr>
            </table>
