knockout.js - Autocomplete updated source is not reflecting in Knockout JS -


i have implemented autocomplete in knockout js project using example

http://cameron-verhelst.be/blog/2014/04/20/knockoutjs-autocomplete/

it working populated source data. later on have changed source data on focus event of text box on autocomplete applied.but auto complete pop not populating updated source data. binding 

<input class="form-control" type="text" style="margin-right:15px;border:0px;" data-bind="value:conditiondata,event:{ focus:assignautocompletearray },autocomplete: {selected:selectedoption, options:options}" placeholder="key">

and changing source way

 self.assignautocompletearray = function (attribute)         {             debugger;             var attr = attribute;             var tokenlistdata = ruletokenlist.map(function (element) {                 return {                     label: element.label,                     value: element.value,                     object: element                 };             });             attribute.options = ko.observablearray(tokenlistdata);         }

my view model 

var criteria = function () {         debugger;         var self = this;         self.id = ko.observable();         self.conditiondata = ko.observable();         self.value = ko.observable();         self.andor = ko.observable();         self.operator = ko.observable();         self.children = ko.observablearray([]);         self.andorlist = ko.observablearray([{ key: 'and', value: 'and' }, { key: 'or', value: 'or' }]);         self.operators = ko.observablearray(operatorlist);         self.isactive = ko.observable();         self.isvisibleaddchild = ko.observable(false);         self.selectedoption = ko.observable('');         self.options = ruletokenlist.map(function (element) {             return {                 label: element.label,                 value: element.value,                 object: element             };         });         self.addchildattribute = function () {             var newattr = new criteria();             self.children.push(newattr);         }          self.savefilter = function (attribute) {             self.isvisibleaddchild(true);         }          self.assignautocompletearray = function (attribute)         {             debugger;             var self = this;             var tokenlistdata = ruletokenlist.map(function (element) {                 return {                     label: element.label,                     value: element.value,                     object: element                 };             });          }     }

what issue

thanks utpal

you replacing observablearray instead of changing out contents. 1 knockout had bound no longer there. should do

attribute.options(tokenlistdata);

to give new contents.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
