Description of problem:
In a test run's clone page, the number showing selected cases to be cloned is not changed along with removing cases by clicking Remove button in each line of the bottom case table.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Open a test run containing several cases (assuming there are more than 5 cases)
2. Select 5 cases
3. Click Clone button
4. In the clone page, text "Selected cases 5:" appears
5. Remove some case by clicking Remove button
Number 5 is still there without change
Number 5 should be reduced and synced with the actual number of remaining cases
in the clone test run page,the selected cases number is also wrong.
1.open a test run with 17 cases,
2.then choose 3 cases and click clone button.
3.in the clone test run page,check the number of selected cases.
step3:in the clone run page,the selected cases number is still 17 not 3
Excepted result:it should be 3 not 17.
