Apparently you're not the only one to encounter this issue. Here are some similar situations:
It appears that no one has found out the solution yet. It doesn't seem to come from jQuery Update or backend theme. However, these advices show up each time:
If you find which module interferes with Views or why JS file is not loaded, I think you will make more than one happy people.
If you're using a custom admin theme, try switching back to Seven theme
I've had same problem.
When I realized that I've added condition to override js file only on add content type event page or on edit page.
So maybe you can check if you are implementing hook_js_alter function and try to comment that out and try again.
Hope this will help someone.
