How do I call a project's button from the html exported?

Hello,

I've found something difficult to archieve in construct 2:

I'm trying to create a button that call a jquery function. So my plan is to write the jquery code in a file and add the url in the index.html obtained by the export.

But, it is possible to get the id of that button or to change it's code so that, when it is clicked, it actives the jquery function?

As far as I know this is called DOM, that mixture of javascript and html, but I can't find the way to mix it with a construct project.

Any idea or experience related to this?
