How to use onBlur in Flask?

Question

JavaScript

Hi, I'm trying to make my flask app work onBlur like normal javascript+html.
The task is to run the validation function when moving from one field to another.
So everything works fine:

<p >Enter an email address:</p>
<input type="text" placeholder="Type your email here..." id="myInput" onBlur="getInputValue()">
<button type="button" onclick="getInputValue();">Validate</button>

<script>
    function getInputValue(){
        
            // some function

        }
 
</script>

But if you switch to flask - it's not clear what to do:

<tr>
            <td>{{form.email.label}}</td>
            <td>{{render_field(form.email)}}</td>
            <td><button type="button" onclick="getInputValue();">check email</button></td>
        </tr>

With a button, everything works if anything, but I would like it without a button, something like this:

<td>{{render_field(form.email(onBlur_="getInputValue()"))}}</td>

and this method doesn't work - I'm "TypeError: 'Markup' object is not callable"

getting this. Can this be done in a flask at all?
Thank you!
