TT#55953 Prevent hiding buttons on ajax search

When clicking into a datatables search field, then moving the mouse over
a result row of a different datatable, then start typing in the search
field, a hover() seems to trigger a handlerOut event, making the buttons
to disappear.

Using two separate onmouseover() and onmouseout() events instead of the
hover() seems to fix this.
