Translate selection fields from another model - Template Website Odoo 11 - templates

Question

I have a selection type field who is coming another model. But, my traduction file do not take it into account. I am looking to find a other solution for translate values fields this select field.
Any idea ?
EDIT :
Here my template code :
...<table class="table table-hover table_requests" id="order_tableau">
<thead>
<tr>
<th scope="col">Reference</th>
<th scope="col">Type</th>
<th scope="col">Applicant</th>
<th scope="col">Date</th>
<th scope="col">State</th>
</tr>
</thead>
<tbody>
<t t-foreach="requests_grc" t-as="request_grc">
<tr id="result_requests" t-att-onclick="'window.location=\'/web#id='+str(request_grc.id)+'&view_type=form&model=website.application&menu_id=299&action=389\''"
t-att-class="'cursor-pointer'">
<td><t t-esc="request_grc.name"/></td>
<td><t t-esc="request_grc.website_application_template_id.name"/></td>
<td><t t-esc="request_grc.applicant_id.name"/></td>
<td><t t-esc="request_grc.date" t-options="{'widget': 'date'}"/></td>
<td><t t-esc="request_grc.state"/></td>
</tr>
</t>
</tbody>
</table>...
Here my Python code :
requests_grc = http.request.env['website.application'].search([])
Result
I would translate the last element on my table : request_grc.state
