Trigger search when submitting search form

[yscik]

Fixes #2304

Changes proposed in this Pull Request

• When using AJAX search, which submits the search whenever an input changes, also do the search when clicking the 'Search Jobs' button

Testing instructions

• Go to the Jobs page and use the search form

Notes

There is a bit of trade-off here. The search so far triggers on change events, which occurs when unfocusing an input. And that happens when the users moves to click the submit button. So in most cases the search would happen anyway. And in fact, with this change, the search request is duplicated, because both the change event and the submit event triggers it.

The code cancels the ongoing search request when a new one is issued, but in this case it might make more sense to only trigger the search on submit when it's not already going on?

I tested this out but on my test site I never see another request happen when clicking "Search Jobs". I can see triggerSearch is called, but it never calls update_results.

Hey @mikeyarce and @yscik, I added a commit which does the following:

• It passes the selected element to triggerSearch to fix the issue that Mikey mentioned above
• It checks if there is a pending search before triggering a new search.

Let me know your thoughts.

Thanks @gkaragia, that's a great approach. Code looks good, but I can't approve as the PR author :)
