Hello Dennis !
Thank you very much for your answer. It's a smart workaround, but unfortunately it doesn't work in my case.

Here is what I tried :

$('.validation_check').click(function(ev) {
$('form').submit();
});

This solution gave me a Bad Request because of csrf token. I then tried to add this in my form:

<input type="hidden" name="csrf_token" t-att-value="request.csrf_token()"/>

Again, unfortunately no luck. When I click the button, I fall on a white page, and the form is not submitted.

Any clue what's happening here ?

Right...
I just did a couple research on Stack Overflow and stumbled on this helpful thread ( [link](https://stackoverflow.com/questions/5384712/intercept-a-form-submit-in-javascript-and-prevent-normal-submission) )
The theme among those answers is that you need to wait for the document or the window object to finish loading first, then move on to the clicking event.
```
$(document).ready(function() {
$('.validation_check').click(function(ev) {
$('form').submit();
});
}

Thanks for the link.
I tried to wait for the load of the document but it didn't seem tobe the issue. In the mean time I went for another solution by heriting an odoo function and call super on it.

Thanks a lot for your time
