Angularjs Return result of a condition comming from a json

I'm working in a app with Angularjs, node and SQL SERVER. I want to calculate the result of a condition that comes from a database field.

var chk = angular.fromJson(item.CHK1);

item.chk1 is a field comming from the database, and its equal to {"validation_cal":"item.QNT_PROPUESTA > 1000","validation_type":"BLOCK","description":"Stock mas de un año"}

So chk.validation_cal is equal to item.QNT_PROPUESTA > 1000 and item.QNT_PROPUESTA is equal to 1200

I've tried: 

console.log($rootScope.$eval(chk.validation_cal));

The result always is "false"

I supposed the problem is that Angular is not really doing the calculation of the condition.

Any help will be appreciate.

Thanks in advance.

It seems that the problem consists of that the scope doesn´t know the value of the field item.QNT_PROPUESTA. The function $eval is trying to evaluate the expression item.QNT_PROPUESTA > 1000 but before this value has to be in the rootScope.

I have tried this and it works:

        var chk = angular.fromJson(item.CHK1);
        $rootScope.item = { QNT_PROPUESTA : 1200 };
        console.log($rootScope.$eval(chk.validation_cal)); // true
