The disableInvalidSubmit=true property of the the options object does not work as expected when the submit button is override through the layout object

To Reproduce

Just create a simple form from a json schema and override the submit button

<json-schema-form [schema]="anySchema" [framework]="'my-framework'" [(data)]="anyData" [layout]="layout"></json-schema-form>

 layout = [
        '*',
        {
            type: 'submit',
            title: 'Create',
            onClick: () => this.http.post<any>(this.endPoint, this.jsonData).subscribe(
                resp => {
                    ...
                }, error => {
                    ...
                })
        }
    ]

Expected behavior
If the form is in invalid state the submit button should be disabled
