I have a razor page called _Upsert page which takes an argument and passes the value to child component by calling the child component and passing the value through it. Normally it should update the child component by calling it's OnParametersSetAsync method as soon as the parent component makes any change to the child component value. But in this code it is not calling OnParametersSetAsync. I have tried everything. Please help me.
Child page - TelerikTextAreaQuickCode.razor

Please help me with this.
