The WordPress Interactivity API uses HTML "directives" to wire a block's markup to a shared store. Two get mixed up. data-wp-text sets an element's text content from a store value. data-wp-bind--<attr> sets an HTML attribute from a store value. Text content is not an attribute, so there is no data-wp-bind--text — if you want to change what an element says, you need data-wp-text.
<span data-wp-text="state.count"></span> <!-- sets the text inside the span -->
<button data-wp-bind--disabled="state.isBusy">Go</button> <!-- sets the disabled attribute -->
data-wp-text element pointing at a store value and confirm the text renders from the store.
Done when: changing the store value updates the visible text with no page reload.data-wp-bind--hidden to an element driven by a boolean in state.
Done when: toggling the boolean shows/hides the element.
