knockout.js - Error when trying to reset knockout observable -

in searching interwebs following code part of view model should work fine:

function myviewmodel() { var self = this;  self.name = ko.observable(); self.displayname = ko.observable(); self.description = ko.observable();  self.save = function () {     $.post('/my/mvccontroler',         { name: self.name(), displayname: self.displayname(), description: self.description() },         function success(data) {              self.name(null);             self.displayname(null);             self.description(null);              $('#mydialog').modal('hide');         }); } } 

however getting error uncaught typeerror: string not function @ name: self.name().

the end goal reset view model on form submission. prefer call ko.applybindings once best practice.

edit: after great answer realized this.name being created string somewhere other code. changing variable name resolved issue.

you must resetting self.name somewhere else in code. mentioned you've tried setting self.name = '' - code still in there? because if so, you're overwriting observable object, , setting string (hence error message of 'string not function').

look through code (or post rest of here), , make sure you're not setting self.name = [anything] elsewhere.
