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>

Answer 2

The code executes line by line. You are triggering the click event before applying the event to the element. This is why no event is being fired and no alert is being launched.
