I have to show some data base on selection drop down list, the form is dynamic, here is my teplates

        function imeiInfo () {    
            $('select').change(function(e) {
                e.stopImmediatePropagation();
                let elm = $(this);
                data = {};
                data[elm.attr("name")] = elm.val();
                $.ajax({
                    url:'/ajax/return_back_imei_plusinfo/',
                    data:data,
                    success:function(data){
                        console.log(data.price)
                        if (data.price){
                            elm.closest("div.child_imeiforms_row").find("input.nrx").val(data.price);
                        }

                        if (data.mobile){
                            elm.closest("div.child_imeiforms_row").find("input.mobile-type").val(data.mobile);
                        }
                    }
                })
            })             
        }
        imeiInfo();

            <button type="button" class="btn btn-lg btn-info" id="add-more-invoice">add new row</button>

            <div class="card-footer">
                <div class="row justify-content-center">
                    <button type="submit" class="btn btn-lg btn-success">save</button>
                </div>
            </div>
        </form>

but it only works well for the first form, after the form, i’ve to select the drop down list in order to return the data !
and here is my views.py

@login_required
def return_back_imei_plusinfo(request):
    query = request.GET
    for item in query:
        if item.startswith("imei-") and item.endswith("-item"):
            item_id = query.get(item)
            break    
    selling_price= Imei.objects.get(id=item_id).mobile.selling_price,
    mobile=Imei.objects.get(id=item_id).mobile.mobile.model,
data = {
    'price' : selling_price,
    'mobile':mobile,
}    
return JsonResponse(data)

and here is my forms.py

class ImeiModelChoiceField(ModelChoiceField):
    def label_from_instance(self,obj):
         return str(obj.imei)

class ImeiInvoiceForm(forms.ModelForm):
    item = ImeiModelChoiceField(queryset=Imei.objects.filter(status=True),widget=forms.Select(attrs={'onchange':'imeiInfo();'}))
    class Meta:
        model = ImeiInvoice
        fields = ['item','price','cash','discount']
        widgets = {
            'price':forms.NumberInput(attrs={'class':'form-control','onkeyup':'totalSum()'}),
            'cash':forms.NumberInput(attrs={'class':'form-control','onkeyup':'totalSum()'}),
            'discount':forms.NumberInput(attrs={'class':'form-control','onkeyup':'totalSum()'}),

    }

is there another way achieve that please !?
thank you in advance ..
