Implement ngonchanges hook inside formly

[Swethasri1512]

I am passing value of form elements disabled state as true or false from parent component.

So in child component I am using @input() disabled :Boolean

First load I am getting value from parent to child but I need to change this disabled state from true to false upon button click .,

Upon buton click the change in disabled state is passed from parent to child as
Parent component
<cm-child [disabled]="disabledstatus">

Child component
@input() disabled : string

This false state is not binding to form elements in ngxformly html elemnts but in child component ngonchanges lifecycle hook I can see disabled value updated once I click button

Is there any way that I can update form elements disabled state once the value is changed from parent component ?
