Hi,
I have binded data using Knockout JS in an MVC4 application.
However, now I am facing issues while doing validation for input elements e.g. textbox at client side using knockout validation plugin.
I want validation in a way which shows value as required and also displays a custom message for that on a button ( not submit button) click event.
Getting error for isValid property : Error: Object doesn't support property or method 'isValid'
Please find below some part of code:
HTML :
<input Go to the complete details ...
