Answer 1

Use .click() instead of .trigger(). And put it after event hanlder declaration.

$(document).ready(function (e) {

    $(".qololbl").click(function(){
        alert("Hi");
     });
     
     $('.qololbl').click();
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input name="radio-choice-t-6" class="qololbl" id="radio-choice-t-6a" value="qolo" checked="checked" type="radio">
<label for="radio-choice-t-6a" style="border: 1px solid #2d5f7c;width:90px;border-bottom-left-radius:4px;border-top-left-radius:4px;font-family:Noto Sans;">Toast</label>
