wicked_pdf gem does not execute formBuilder rendering function

[jedi-032]

Issue description

I'm trying to implement a PDF version of my forms which are created via the plugin jQuery formBuilder v2.1.2.

However, wicked_pdf does not recognize the formBuilder function: $('#fillable-form').formRender(formRenderOpts);

It returns the error TypeError: 'undefined' is not a function (I used this code snippet to debug javascript via console logs).

Please see my Stack Overflow question for more details.

Expected or desired behavior

The form should be rendered out upon generating the PDF but it does not recognize the .formRender() function of formBuilder.

I tried debugging and .formRender() works well in plain HTML format.

wicked_pdf version: 1.4.0
