Embeded Form response very slow

I have create a form https://form.jotform.me/61577990156467.

I tried it directly and seems no problem but when I embedded it in my website, the response during submission of form is very slow/ no response (keep hanging). Do you have any idea on this?

I test your embedded form https://form.jotform.me/61577990156467   on your website http://icim2016.utm.my/paper-submission/  and I was able to encounter the Submit issue as well.

there was an error shown in the browser console

Can you please remove first the embedded form and then re-embed it on your website using its iframe embed code instead.
