Knockout select binding -

how prevent select change event fires when select biding initiated? add button on page add select dynamically dom. when each select box adding dom, change event firing rather select item select?

the thing knockoutjs attempts find element of listbox matches requireditem observable. there none in beginning, why attempts set "caption" of listbox. did not provide one, sets requireditem first element of listbox.

what add caption item array:

self.requireditems = ko.observablearray([ { desc: "select option list...", key: 0, editable: false } // ... , other items]); 

and if don't want requireditem updated:

self.selecteditem = ko.observable(self.requireditems()[0]); 

then if want know if valid element has been selected list, add following property:

self.isvalidselecteditem = ko.computed(function() {       return self.selecteditem().id;  });
