Issue with Angular2 input not firing the change event

I am facing an issue where the (change) event is not triggered when updating an input field that is being updated from a query.

Here is the HTML code for the input:

<input type="text" [ngModel]="inputValue" id="itemText" (ngModelChange)="setNewItem($event)">

This is the function in the component file related to the input:

setNewItem(item){
console.log("Triggered");
return this.ds.setItem(item);  
}

The input field is being updated in the index HTML using the following script:

 <script>
 ....
 onSelect: function (request, response) {
        var urlApi = 'http://localhost:8088/Badges/Details/' + request.item;
                   $.ajax({
                    type: "GET",
                    url: urlApi,
                    dataType: 'json',
                    success: function(response) {
                      document.getElementById("itemText").value = response.items[0].item; } 
     }); 
}
</script>

Answer №1

Avoid doing this,

document.getElementById("itemText").value = data.items[0].element;

Instead, consider assigning the value directly to the binding property (this should be handled at the component level to ensure access to the inputValue),

this.inputValue = data.items[0].element;

Also, make sure to utilize the 2-way binding syntax.
