AngularJS : ng-model binding not updating when changed with jQuery

Viewed 187842

This is my HTML:

<input id="selectedDueDate" type="text" ng-model="selectedDate" />

When I type into the box, the model is updated via the 2-way-binding mechanism. Sweet.

However when I do this via JQuery...

$('#selectedDueDate').val(dateText);

It doesn't update the model. Why?

You have to trigger the change event of the input element because ng-model listens to input events and the scope will be updated. However, the regular jQuery trigger didn't work for me. But here is what works like a charm

$("#myInput")[0].dispatchEvent(new Event("input", { bubbles: true })); //Works

Following didn't work

$("#myInput").trigger("change"); // Did't work for me

You can read more about creating and dispatching synthetic events.

Just use:

$('#selectedDueDate').val(dateText).trigger('input');

instead of:

$('#selectedDueDate').val(dateText);
