import {
    FormsModule
} from '@angular/forms';
import {
    NgxDynamicFormCreatorModule
} from 'ngx-dynamic-form-creator'
import {

HTML:

< ngx-dynamic-form-creator [dynamicForm]="dynamicForm" [settings]="settings" [onSubmit]="onSubmit.bind(this)" >
    < /ngx-dynamic-form-creator>

Typescript: recommend to use the types

onSubmit(values: any) {
    // do something
}

  settings: ISettings = {
      buttonText: {
          back: 'back',
          done: 'save',

      position: 'horizontal',
      stepperClassName: 'stepper-field',
