Hi @Ankur Bawiskar 

I was able to get that using below script in client controller

function($scope) {
         var c = this;
         $scope.$watch(function () {
                   return $scope.page.g_form.getValue('name_of_variable');
         }, function (value) {
         c.data.message = value;
});
}

This script will instantly set the updated value of variable to c.data.message which I can access in html.

This works fine for one variable but I want to make it work for multiple variables. How can I do that? I have the variable names in an array.
