Django/Bootstrap: form-check-inline not working

EDIT 1

I've tryed using bith crispy-forms and widegt-tweaks but it doen't works.

Seems that widget=forms.RadioSelect() is not compatible with use of these 2 libraries together...

I want to display radio button inline using Boostrap.

I've tryed to add bootstrap form-check-inline class by setting attrs attribute of Django widget.

But When I debug, form-check-inline is not applyed. If I add form-check-inline class "manually" in div element containing radiobutton (see below) it works.

template.html

{{ form.eli_oui_ebo|as_crispy_field }} 

html page when inspected

<div class=""> ***<= here should be applyed form-check-inline class**** <div class="form-check"> <label for="id_id_eli_oui_ebo_0_1" class="form-check-label"> <input type="radio" class="form-check-input" name="eli_oui_ebo" id="id_id_eli_oui_ebo_0_1" value="0" class="test"> Non </label> </div> <div class="form-check"> <label for="id_id_eli_oui_ebo_0_2" class="form-check-label"> <input type="radio" class="form-check-input" name="eli_oui_ebo" id="id_id_eli_oui_ebo_0_2" value="1" class="test"> Oui </label> </div> </div> 

form.py

self.fields['eli_oui_ebo'] = forms.TypedChoiceField(label = 'A eu, dans les 72h, un contact avec un malade Ebola confirmé par RT-PCR',widget=forms.RadioSelect(attrs={'class': 'form-check-inline'},),required=False,choices=[i for i in Thesaurus.options_list(1,'fr') if i != (None,'')], empty_value=None, disabled=DISABLED)```
