Refresh all form fields

Hello all,
I use “Contact Form 7 Multi-Step Forms” plugin to create a multi-step form. The problem is that when the user gets back or even reloads the first form page, the fields on it have the values existing in the beginning.
To fix this, I need to reset all form fields when the form loads.
I can use JavaScript document.getElementById(“myForm”).reset(); on form load.
The problem is that I don’t have the elementId of the form. I looked at the code generated by contact form 7 and there is no id=”” defined when creating the form. Is it possible that I set id somehow so I can do the rest?
Thanks in advance
