$('button').on('click', e => { alert('you clicked a button!') })
$(document.body).append($('<button></button>').text("I've been added from JavaScript"))

If you click on the button that says I've been added from JavaScript, no alert will pop up, I think you understood that.

So, the solution is to listen click on the body, and check if the target was a button. jQuery allows you to do it like so:

$(document.body).on('click', 'button', e => { alert("you clicked a button!") })

For more about $.on().

Without jQuery (because sometimes it's helpful to understand how to magic happens)

document.body.addEventListener('click', e => {
    // e.target is the clicked element
    // in our case, we just want to check if the tag name is `button`
    if (e.target.nodeName != 'BUTTON') {
        return // stop the function
    }

    alert("you click a button!")

})

e.target.nodeName is always upper cased (you can call .toLowerCase() upon it if you want to)

You can try this

$("body").on("click", "#tab_logic .del",
    function() {
      alert("i am"); // add code here 
});
