Delete class item dynamiclly


in my ionic project I’m using a toggle the generated html of this toggle is:<div class="item-toggle toggle-large ng-valid ng-empty item item-toggle" id="dd" ng-class="checkarrivee.ficheDeMission==undefined ? 'item' : ''" ng-model="[]" ng-click="checkarrivee.isMissionSelected(," toggle-class="toggle-positive"><div ng-transclude=""><span class="ng-binding">Ceintures De Sécurités Passagères</span></div><label class="toggle toggle-positive disable-user-behavior"><input type="checkbox" ng-model="[]" class="ng-pristine ng-untouched ng-valid ng-empty"><div class="track"><div class="handle"></div></div></label></div>

is there a way to check item class dynamiclly, because i dont want the item class to appear in my div, i tried to use ng-class but it didnt work, how i can get div without item class???
