App got stuck in login page after 2-3 wrong password attempt

I’m working with ionic 3 and angular 2 and created one small app. In login page if I entered 2-3 times wrong password then it got stuck on same page and I’m unable to enter password again, means I can’t type anything in password box.

Can anyone please tell me what should I do ?

What login page are you talking about?

I’ve created login page which is root page of my app.
