I have a TypeError when column is frozen and I refresh columns

I have an error: 

TypeError: this.parent.headerModule.getMovableHeader is not a function

getColumn(columnName: string) {
return this.treegrid.getColumnByField(columnName);
}

contextMenuClick(arg?: any) {
if(arg) {
this.actionToDo = arg.item.properties.id;
}
if(this.actionToDo === 'EditCol' || this.actionToDo === 'NewCol' || this.actionToDo === 'DeleteCol') {
this.onOpenDialog(arg)
} else {
const column = this.getColumn(this.columnNameForManipulations);
column.isFrozen = true;
this.treegrid.refreshColumns();
}

}
