ko.observableArray does not trigger subscribe event if I push any items to array

[Tirumal Sutrave]

I have observable array and have subscribed a callback in it. Callback is not triggered if I push items to observable array. Did not quite get why? am I missing anything here.

[Gunnar Liljas]

Please show a bit of code.

this.data = ko.observableArray([]);
this.data.subscribe(function(newValue){

console.log('This does not execute.');

});

self.data().push('Any random text');

You are calling push method of js array, wrapped by observableArray. In order for everything to work as intended you should call push of observableArray:

self.data.push('Any random text');
