Activate search from form inputs

I have a form built with the calculated form fields plugin for selecting drive end information above a table. When selecting options from the form the information is added to the search box but the search is not activating unless I click inside it or press a key on my keyboard.

Is there a way I can activate the search without manually interacting with the search box?

<script type="text/javascript">


function displayColumns() {

//  console.log(jQuery("#fieldname13_1").val());
//  jQuery("fieldname13_1").val('Ft-Lb (Foot-Pound)').trigger('change')
//  var val='Ft-Lb (Foot-Pound)';
//  jQuery("fieldname13_1").trigger("change").val('Ft-Lb (Foot-Pound)');


//jQuery('.ninja_column_2').hide();
//jQuery('.ninja_column_3').hide();
//jQuery('.ninja_column_4').hide();
//jQuery('.ninja_column_5').hide();
//jQuery('.ninja_column_6').hide();
//jQuery('.ninja_column_7').show();

//jQuery('.ninja_column_2').css("display","none !important");
//jQuery('.ninja_column_3').css("display","none !important");
//jQuery('.ninja_column_4').css("display","none !important");
//jQuery('.ninja_column_5').css("display","none !important");
//jQuery('.ninja_column_6').css("display","none !important");
//jQuery('.ninja_column_7').css("display","none !important");

//jQuery('.ninja_column_2').css("visibility","hidden");
//jQuery('.ninja_column_3').css("visibility","hidden");
//jQuery('.ninja_column_4').css("visibility","hidden");
//jQuery('.ninja_column_5').css("visibility","hidden");
//jQuery('.ninja_column_6').css("visibility","hidden");
//jQuery('.ninja_column_7').css("visibility","hidden");

//jQuery(".ninja_column_2").addClass("hide_all");
//jQuery(".ninja_column_3").addClass("hide_all");
//jQuery(".ninja_column_4").addClass("hide_all");

//jQuery("td .ninja_column_5").addClass("hide_all");
