md-input value update issue

[junaidurfjd]

md-input remains focused even if the the text is deleted. i.e if I type "hello" and then remove it the input remains as it is focused.. and also the class "md-input-has-value" remains on the parent md-input-group element"

The issue lies somewhere with peace of code..

 // angular-material.js line 3930
  element.on('input', function() {
    var value = element.val();

    inputGroupCtrl.setHasValue(angular.isDefined(value) && value!==null);
  });

@Darwesh27 - if you delete the input text, why would it not remain focused?
The other issue is a bug.

The problem is.. Even if I delete the input text and leave the input box.. It still remains focus.. IMO the model provided to it never becomes null. As to loose focus the model has to be null according to the code.
