Click events lost

[Dhana]

Steps to reproduce

1. editor.insertHtml is used in my code to insert span element with onclick attribute there.
2. Switch to 'Source' in toolbar, click on it again to see the editor area
3. Now we have lost the click event, clicking span element no longer triggers click event.

Expected result

Actual result

Other details (browser, OS, CKEditor version, installed plugins)

Also, when I saved the ckeditor content, reload the page, all the click events are lost.

You need to learn about ACF:

​​http://docs.ckeditor.com/#!/guide/dev_advanced_content_filter
​​http://docs.ckeditor.com/#!/guide/dev_disallowed_content
​​http://docs.ckeditor.com/#!/api/CKEDITOR.filter-method-addTransformations

​​http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-extraAllowedContent
​​http://nightly.ckeditor.com/14-03-20-07-05/full/samples/datafiltering.html

This configuration prevents removing onclick handler:

var editor = CKEDITOR.replace( 'editor1', {
	extraAllowedContent : '*[onclick]'
});

Please also note that onclick will not work in design mode (for security reasons). You need to preview the page in order to see result.
