angularjs - How to forbideen updating model in Angular JS? -

i have nested controller like:

<div ng-controller="maincontroller">    <div ng-controller="childcontroller"></div> </div> 

inside child controller there function:

$scope.isstatus = function() {     return function(item) { }}; 

this function used in ng-repeat.

so, problem when modify model of controller maincontroller reload model of childcontroller, means function isstatus() works again , reload model. how fix it?

you can use controlleras syntax avoid this

  <div ng-controller="maincontroller main">        <div ng-controller="childcontroller child">    <ul ng-repeat ="item in child.item"> </div>     </div> 

and in js

function childcontroller (){  var vm = this; vm.isstatus = function() {     return function(item) { }}; }
