Remove specific event handler from child of element

Question

In my application I want to resize a window when user clicks on panel-heading, but that heading contains a child element- button which has another event handler binded on. What I need to do is, when user click on that button, no resize function will be called. I tried many variations, but none of them worked.

HTML:

<div class="panel-heading" style="cursor:pointer">
   <div class="pull-right">
       <button type="button" class="btn btn-danger btn-xs" id="btn-subject-remove"><span class="glyphicon glyphicon-remove"></span> Remove</button>
   </div>
</div>

And my jq is:

$('#btn-subject-remove').on('click',btnRemoveSubjectsClick);
$('#subscribers-row .panel-heading').on('click',btnResizeClick);

What I have tried, but none of them worked:

 $('#subscribers-row .panel-heading').off('click','#btn-subject-remove',btnResizeClick);
 $('#btn-subject-remove').off('click',btnResizeClick);
 $('#subscribers-row .panel-heading').on('click',btnResizeClick).children().click(function(e){return false});

I also tried checking in btnResizeClick function what element was clicked, and if it was remove button then return false, but the clicked element is still panel-heading

Any suggestions?

Bind a click event on the children and use e.stopPropagation() to block the parent click event.

In a simple example:

 $(function() { $('div').on('click', function() { $(this).toggleClass('redBg'); }); $('div>*').on('click', function(e) { e.stopPropagation(); }); }); 

 div { background: green; width: 200px; height: 200px; } span { display: block; height: 50px; background: yellow; } .redBg { background: red; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div> With some text <span> in a span </span> </div>
