React – State not updated

by

From the reactjs docs:

setState() does not immediately mutate this.state but creates a pending state transition. Accessing this.state after calling this method can potentially return the existing value.

What you can do is pass a callback function to setState which is triggered once the state has been updated:

this.setState(
    {autocomplete_from: ...}, 
    function () {
        ... at this point the state of the component is set ...
    }
)
