Ember JS 2 Changes to HTML got erased after rerender

Ember 2. I have a template where I display my model data. And I have a JS script that makes some changes to HTML (inits some JQuery plugins etc), and I need to run it every time I render the view.

I trigger it in the didRender hook of my view. It works fine on the first load. But when I visit the page second time, I can see that plugins are initializing, but in the next moment all changes disappear and the page is as it was initially in the template.

I guess that there is something that looks for changes in the model and re-render the page after it was rendered in the second time, but I'm not sure about it. I tried to listen for other hooks, like didUpdate, but they are not triggering.

What could be a reason of such strange behaviour?
