javascript - How to properly update a scope variable if it's being passed as a parameter -

i'm trying pass scoped object property function in controller , change value either true or false depending on current value. want value updated in scope @ same time.

the problem occurs can't use $scope.isbeingedited in function update scope, because it's present in ng-repeat wouldn't know 1 update. , setting value of parameter doesn't seem update scope.

i read this question seems state not possible? maybe read wrong surely there must rather simple way of achieving this? causing me problems on more 1 front it's time solve issue.

here's dumb version of markup, containg title, input , edit "button":

<div ng-repeat="bodypart in body">   <h3 ng-hide="bodypart.isbeingedited" ng-bind="bodypart.name"></h3>   <input ng-show="bodypart.isbeingedited">   <span ng-click="seteditstate(bodypart.isbeingedited)">edit</span> </div> 

when click on "edit" should run, passing bodypart.isbeingedited variable value check for:

$scope.seteditstate = function(item) {    // check if item true or false   // , set accordingly   item ? item = false : item = true; } 

how can ensure scoped variable gets passed function gets updated when item gets updated?

you can pass item instead of property isbeingedited , use in code accordingly:

<span ng-click="seteditstate(bodypart)">edit</span> 

controller

$scope.seteditstate = function(item) {   item.isbeingedited = !item.isbeingedited; }
