code example below:

<div class="form-floating mb-3" data-controller="home">
    <input type="text"
           class="form-control autoplete-input"
           id="city" placeholder="Vila Mariana"
           data-home-target="district"
           data-action="keyup->home#autoComplete" />
    <label for="city">Bairro</label>
    <div class="autoplete-body">
        <ul>
            {#for state in states}
                <li data-home-states-value="{state.uf}"
                    data-home-name-value="{state.name}"
                    data-action="click->home#selectItem">
                    {state.name}
                </li>
            {/for}
        </ul>
    </div>
</div>

The ul:li element is already inside a data-controller=home scope but it fails to capture the value of li. It only works if I declare:

{#for state in states}
    <li
        data-controller="home"
        data-home-states-value="{state.uf}"
        data-home-name-value="{state.name}"
        data-action="click->home#selectItem">
        {state.name}
    </li>
{/for}

code example below:

<div class="form-floating mb-3" data-controller="home">
    <input type="text"
           class="form-control autoplete-input"
           id="city" placeholder="Vila Mariana"
           data-home-target="district"
           data-action="keyup->home#autoComplete" />
    <label for="city">Bairro</label>
    <div class="autoplete-body">
        <ul>
            {#for state in states}
                <li data-home-states-value="{state.uf}"
                    data-home-name-value="{state.name}"
                    data-action="click->home#selectItem">
                    {state.name}
                </li>
            {/for}
        </ul>
    </div>
</div>

        data-controller="home"

        data-action="click->home#selectItem">
        {state.name}
    </li>
{/for}

I believe by design is must be in the same element as the controller definition.

Looking at the values documentation, It is purposefully put in the same element as the controller definition.

Where as the in the targets documentation, the targets are put in child elements.

I was having the same issue as you; the above is the conclusion I came to after way too much googling, and messing around with my own code. Though, I was unable to find a concrete definition anywhere on if this is expected behavior.

If you want to access that data you always define a target, or multiple, and access the data on that.

Setting in html:

data-home-target="abc"

Assign in controller:

static targets = ["abc"]

Access in controller:

this.abcTarget.dataset['dataname']

It looks like you might want to be accessing the data on an event click?

You could also do this in the event handler:

event.target.dataset['dataname']
