html:

controller:

$scope.items = [];       $rootscope.couponlist = [{ coupontitle: "purchase worth $100", data: {description: "$50 off", fromldate: "2016-09-09", todate: "2016-09-18"}},       {coupontitle: "purchase worth $300",  data:{description: "$75 off", fromldate: "2016-11-09", todate: "2016-10-19"}},       { coupontitle: "purchase worth $500",data:{description: "$95 off", fromldate: "2016-09-10", todate: "2016-09-30"}}];        $scope.select_item = function (key) {         $scope.items.push(key);        }   $scope.deleteselected = function () {            $scope.items.splice($scope.items.indexof());     }

as suggested in 1 answer can use $index mechanism remove object array.

you have delete both items array , rootscope array

view:

<ion-option-button class="button-assertive" ng-click="deleteselected($index,coupons)">delete</ion-option-button>

controller:

 $scope.deleteselected = function (index,coupons) {      $rootscope.couponlist.splice(index,1);       var to_delete = $scope.items.find(find_data)       function find_data(items) {          return items.coupontitle === coupons.coupontitle;      }       var index = $scope.items.indexof(to_delete);       $scope.items.splice(index,1)    }

here partial implemented fiddle

you should delete both items array , also, couponlist remove in ng-repeat
