the ui not update

[johnqiuwan]

const droppedComponents = componentsTree(state => state.components);
const addComponent = componentsTree(state => state.addComponent);

const newComponent: DroppedComponent = {
            id:  '123',
}
addComponent(newComponent);

while the ui is not update, the store data has updated. It could be proved by using

componentsTree.subscribe(
    (state: any) => {
        console.log(state.components);
    },
);
