How to call blur event from JS file while writing Qunit test case

I have custom search.JS file and contents in JS file as below:

$(document).ready(function () {

$("#number_c").blur(function(){
toggle($("#number_c"),[$("#number_a"),$("#number_b")]);    
});
function toggle(input1, inputs) {
if (input1.val() != '' ) {
for (var i = 0; i < inputs.length; i++ ) {
input = inputs[i];
input.val('');
input.prop("disabled",true);
}
} else {
for (var i = 0; i < inputs.length; i++ ) {
input = inputs[i];
input.removeAttr("disabled");
}
}
}

});

I need to write Qunit test case to call blur method. I tried to trigger blur event in Qunit test case JS file but not able to call search.js blur event.Please suggest me how I can write.Thanks in advance.
