Improve support for multiple calls to `oTracking.click.init`.

notlee commented 3 years ago

Reused any existing clicks queue.
Reuse any existing event delegate.
Do not run the same callback on page view multiple times.

This will allow projects to track clicks on elements which are not tracked with the default oTracking.click.init call, and allow projects to track clicks with different event categories.

For example to track non-interactive elements with the custom data attribute data-my-element-to-track-clicks-on.

oTracking.click.init(
    'my-custom-category',
    '[data-my-element-to-track-clicks-on]'
);
