Cannot set Checkbox with ngmodule

Hey Guys!

In my APP I am trying to show a list with Checkboxes and a label, and i am reading the data out of a database so that i know which checkboxes should be checked and which not.
I am reading them correct out of the DB but it deos not show up correct in the APP…

I am calling this method in my Constructor:
var test is just for testing

    this.allquestions = [];

    var getFeedback = new XMLHttpRequest(); // a new request"GET","http://api/question" ,false);

    var newdata = JSON.parse(getFeedback.responseText);

    for(var i = 0; i <; i++){
      var test = false;
      if(i % 2 == 0){
        test = true;
        value: test

This is the code in my HTML:

<ion-item *ngFor="let item of allquestions">
  <ion-label text-wrap>{{item.value}}</ion-label>
  <ion-checkbox name="check" [(ngModel)]="item.value" name="neededCheckboxName"></ion-checkbox>

At the moment it looks like this:

So as you can see the true values arent checked, but if i am filling the value with true only values it shows up correct:


Does anybody know a solution for this?
