</div>

$('.body-action-button').click(function(){
        alert('selected');//This alert for testing
    });

Answer 1

Try this ( fiddle ): JS

$('input:checkbox[name=example]').each(function() {
  if (this.checked) {
    alert("selected");
  }
  // else {}
});

HTML

<input type="checkbox" name="example" /> label one
<input type="checkbox" name="example" checked/> label two

Answer 2

You can try to give a class to your checkboxes like

<input type="checkbox" class="cbxTest" style="float: left;" name="companies[]" value="<?php echo $company->id; ?>" id="cbtest<?php echo $company->id; ?>" />

and add your event to JQuery like that:

$(document).ready(function () {
    $(".cbxTest").click(function () {
        if (this.checked) {
            alert("Selected");
        }
    });    
});

Also if you want to not trigger it on click but only when checked you can also use .check instead of .click like that

$(document).ready(function () {
    $(".cbxTest").change(function () {
        if (this.checked) {
            alert("Selected");
        }
    });    
});

Both works well. It's just about the scenerio...
