'React: How to create state dependent function in functional components?

In my application I have component like that:

const MyComponent = props => {

    const { attrOneDefault, attrTwoDefault, formControl } = props;  
    const [inputValue, setInputValue] = useState({
        attr_one: attrOneDefault,
        attr_two: attrTwoDefault
    });

    const getValue = ( attr ) => {
        return inputValue[attr];
    }
    const setValue = ( attr, val ) => {
        if( attr === 'attr_one' ) {
            if( val === 'bar' && getValue(attr) !== 'foo' ) {
                val = 'foo bar';
            }
        }
        setInputValue( {...inputValue, [attr]: val} );
    }

    useEffect( () => {
        if( formControl ) {         
            Object.keys(inputValue).forEach( attribute => {
                formControl.subscribeToValueCollecting( attribute, () => {
                    return getValue(attribute);
                });
                formControl.subscribeToValueChange( attribute, ( value ) => {
                    setValue( attribute, value );
                    return true;
                });
            });
        }

        return () => { 
            if( formControl ) {
                Object.keys(inputValue).forEach( attribute => formControl.unsubscribe(attribute) );
            }
        }
    }, []);

    return (
        <div class="form-field">
            <input
                type="text"
                value={getValue('attr_one')}
                onChange={ e => setValue('attr_one', e.target.value)}
            />
            <input
                type="checkbox"
                checked={getValue('attr_two')}
                onChange={ e => setValue('attr_two', !!e.target.checked)}
            />
        </div>
    );
}

And inside functions setValue and getValue I always have default values in inputValue - I can't get updated state inside this functions. How i can organize my code to solve this problem?

P. S.

1) With useCallback I have the same results:

const getValue = useCallback( ( attr ) => {
    return inputValue[attr];
}, [inputValue]);
const setValue = useCallback( ( attr, val ) => {
    if( attr === 'attr_one' ) {
        if( val === 'bar' && getValue(attr) !== 'foo' ) {
            val = 'foo bar';
        }
    }
    setInputValue( {...inputValue, [attr]: val} );
}, [inputValue]);

2) With useEffect functions setValue and getValue are unavailable at first render:

let getValue, setValue;
useEffect( () => {
    getValue = ( attr ) => {
        return inputValue[attr];
    }
    setValue = ( attr, val ) => {
        if( attr === 'attr_one' ) {
            if( val === 'bar' && getValue(attr) !== 'foo' ) {
                val = 'foo bar';
            }
        }
        setInputValue( {...inputValue, [attr]: val} );
    }
}, [inputValue]);

Try this:

const getValue = ( attr ) => {
        return inputValue[attr];
    }
const getValueRef = useRef(getValue)
const setValue = ( attr, val ) => {
        setInputValue( inputValue =>{
            if( attr === 'attr_one' ) {
                if( val === 'bar' && inputValue[attr] !== 'foo' ) {
                    val = 'foo bar';
                }
            }
            return {...inputValue, [attr]: val} );
        }
}

useEffect(()=>{
    getValueRef.current=getValue
})

    useEffect( () => {
        const getCurrentValue = (attr)=>getValueRef.current(attr)
        if( formControl ) {         
            Object.keys(inputValue).forEach( attribute => {
                formControl.subscribeToValueCollecting( attribute, () => {
                    return getCurrentValue(attribute);
                });
                formControl.subscribeToValueChange( attribute, ( value ) => {
                    setValue( attribute, value );
                    return true;
                });
            });
        }

        return () => { 
            if( formControl ) {
                Object.keys(inputValue).forEach( attribute => formControl.unsubscribe(attribute) );
            }
        }
    }, []);
