One click() counts as 11 events in Analytics

One click() counts as 11 events in Analytics

I'm trying to track a simple search form click in Google Analytics.
$('#SearchButton').click(function() {
ga('send', 'event', 'Search Location', 'Click', 'Search Location');
});
<form action="#" id="myform" class="uk-form" onSubmit="getbases2(); return
false;">
<input type="text" id="search" class="uk-form-width-medium">
<input type="submit" value="Search" id="SearchButton" class="uk-button
uk-button-success search-button" />
</form>
Each click on this button counts as 11 events in Analytics. When I changed
the method to mousedown, each click count as 7 events. How can I set this
up so each click on the button counts as only one event?
