Laravel + Vue Lang.js Localization

Question

I’m having trouble translating my page using the Lang.js in the Laravel.

I need to get the chosen language in the user settings using the Axios, and translate using a filter Vue.

The function responsible for collecting the language chosen by the user is the getLanguage(), which is in the created hook.

After collecting the data, I saved config.linguagem and then I change the language using the Lang.setLocale().

However, when I check via console the chosen language, on mounted hook, he chooses the standard language "en", as if I haven’t set the user language.

What am I doing wrong?

    <template>
    <table class="display table table-striped">
        <thead>
            <tr>
                <th>ID</th>
                <th>{{ 'cptasks.gerentes.nome' | trans }}</th>
                <th>{{ 'cptasks.gerentes.email' | trans }}</th>
                <th>{{ 'cptasks.gerentes.categoria' | trans }}</th>
                <th>{{ 'cptasks.gerentes.opcoes' | trans }}</th>
            </tr>
        </thead>
        <tbody>
            <tr>
               <th colspan="5">...</th>
            </tr>
        </tbody>
        <tfoot>
            <tr>
                <th>ID</th>
                <th>{{ 'cptasks.gerentes.nome' | trans }}</th>
                <th>{{ 'cptasks.gerentes.email' | trans }}</th>
                <th>{{ 'cptasks.gerentes.categoria' | trans }}</th>
                <th>{{ 'cptasks.gerentes.opcoes' | trans }}</th>
            </tr>
        </tfoot>
    </table>

        watch: {

        filters: {

                return Lang.get(value);
            }
        },
