problem with an integration of SVG in html

Hello i've got some problems with the integration of svg in a html page. I've learnt that i had to use a "<object>" or a "<embed>" tag to do it. That works fine, but I would like to use a "onChange" attribute to launch a javascript when the user clicks on the svg drawing. I tried to put the onChange attribute on both of the <object> and <embed> tag but the mouse click is never detected. Why? How can I make my svg clickable without writing into its code.
Thanks

With script in html you can add event to your embedded svg with addEventListener.

See

and click on addEventListener for example

do not use <object>,
use<embed>
<embed width="750" height="500" src="catalog.svg" type="image/svg+xml" />
