Answer 1

You forgot to bind your handleSubmit function to the class. You can either use arrow function to define the function.

handleSubmit=(data) =>{
...
}

Or you can bind the function in your constructor.

constructor(props) {
        super(props);
        this.state = {
          updateClothingItem: {}
        };
        this.handleSubmit= this.handleSubmit.bind(this,data);
    }
