Why does the second input textfield in material component not working?

I have used material component input in my website. I create two the same input. Here is all my code:

<link rel="stylesheet" href="https://unpkg.com/material-components-web@latest/dist/material-components-web.min.css">
<body>
    <div class="information">
        <label class="mdc-text-field mdc-text-field--outlined">
            <span class="mdc-notched-outline">
                <span class="mdc-notched-outline__leading"></span>
                <span class="mdc-notched-outline__notch">
                    <span class="mdc-floating-label" id="first">First</span>
                </span>
                <span class="mdc-notched-outline__trailing"></span>
            </span>
            <input type="text" class="mdc-text-field__input" aria-labelledby="first">
        </label>
    </div>
    <div>
        <label class="mdc-text-field mdc-text-field--outlined">
            <span class="mdc-notched-outline">
                <span class="mdc-notched-outline__leading"></span>
                <span class="mdc-notched-outline__notch">
                    <span class="mdc-floating-label" id="second">Second</span>
                </span>
                <span class="mdc-notched-outline__trailing"></span>
            </span>
            <input type="text" class="mdc-text-field__input" aria-labelledby="second">
        </label>
    </div>

    <script src="https://unpkg.com/material-components-web@latest/dist/material-components-web.min.js"></script>
    <script>
        mdc.textField.MDCTextField.attachTo(document.querySelector('.mdc-text-field'));
    </script>
</body>

But just my first input is working properly (the label move to top when I click on). And the second seemd to not have the same effect like that:

What is problem? Thanks.

Solution

It seems that mdc.textField.MDCTextField.attachTo(document.querySelector('.mdc-text-field')); only applying to only one elament.

So i modified the code to make two of the inputs to apply the script as shown below

<link rel="stylesheet" href="https://unpkg.com/material-components-web@latest/dist/material-components-web.min.css">
<body>
    <div class="information">
        <label class="mdc-text-field mdc-test1 mdc-text-field--outlined">
            <span class="mdc-notched-outline">
                <span class="mdc-notched-outline__leading"></span>
                <span class="mdc-notched-outline__notch">
                    <span class="mdc-floating-label" id="first">First</span>
                </span>
                <span class="mdc-notched-outline__trailing"></span>
            </span>
            <input type="text" class="mdc-text-field__input" aria-labelledby="first">
        </label>
    </div>
    <div>
        <label class="mdc-text-field mdc-test2 mdc-text-field--outlined">
            <span class="mdc-notched-outline">
                <span class="mdc-notched-outline__leading"></span>
                <span class="mdc-notched-outline__notch">
                    <span class="mdc-floating-label" id="second">Second</span>
                </span>
                <span class="mdc-notched-outline__trailing"></span>
            </span>
            <input type="text" class="mdc-text-field__input" aria-labelledby="second">
        </label>
    </div>

    <script src="https://unpkg.com/material-components-web@latest/dist/material-components-web.min.js"></script>
    <script>
        mdc.textField.MDCTextField.attachTo(document.querySelector('.mdc-test1'));
        mdc.textField.MDCTextField.attachTo(document.querySelector('.mdc-test2'));
    </script>
</body>
