You need to manually call $scope.$apply();

in the callback function

Or use $timeout

Use $timeout:

app.controller('myinfoCtrl', ['$scope','$timeout'],function($scope,$timeout) {
    $scope.on=true;
    $timeout(function(){
        $scope.on=false;
    },1000)
}

Changing the variables bound in $scope directly in setTimeout will not trigger the dirty data check of the variables. Variable changes will not be synchronized to the interface, so the interface will not make changes.

I have never used setTimeout, but changing setTimeout to $timeout can achieve the effect you mentioned

app.controller('myinfoCtrl', ['$scope'],function($scope) {

$scope.on=true;
setTimeout(function(){
    $scope.$apply(function(){
        $scope.on=false;
    });
},1000)

}
Using setTimeout will not trigger the $digest loop. It is recommended to use the $timeout packaged in angular
