How to make an input touched or dirty programmatically in Angular2?

Question

Angular

I know it sounds dumb. But it so happened that one jquery plugin needs to be friends with Angular2. In general terms, this plugin creates a copy of a piece of html that has inputs. When changing data in angular, it is re-rendered with all errors, etc. But it is necessary that the data was thrown in the opposite direction. I did it via ControlGroup.controls['control_id'].updateValue(value,{emitEvent,emitModelToViewChange}).
All is well, the data is coming. But the angular input where I push the data does not become dirty or touched, but I need it to display errors. How to make an input become touched or dirty? Thanks in advance.
PS: I know that this is not correct, but so far it's the only way
