plus the function mentioned ("cButton") is defined in another function inside the java script file.

(function () {
    var thecid = 0;

    function cButton (ii) {
        document.getElementById(ii).style.display = 'none';
        alert('fdgfg');

        var newcommhtml = '<div id="c0' + thecid + '" class="cnew clearfix">';
        var ii='c0'+thecid;
        newcommhtml += '<section class="c-content">';
        newcommhtml += '<a href="#" onclick="cButton(\'' + ii + '\');" style="color:black;">x</a>';
        newcommhtml += '<p>' + nl2br(textval) + '</p> </section></div>';        
    });
})()

Answer 1

For the onclick to work, you need your cButton() to be accessible globally as a property of the global window object.

Change you code to:

window.cButton = function(ii) {
   ...
}

Answer 2

The problem is that you are defining cButton inside the document ready handler, so it doesn't exist outside that. If you declare the function outside then things can access it later...

function cButton(ii){
    document.getElementById(ii).style.display = 'none';
    alert('fdgfg');
}

(function(){
    var thecid = 0;
    $("#subber").on("click", function(){
        var thelm = "#c0"+thecid;
        var newcommhtml = '<div id="c0'+thecid+'" class="cnew clearfix">';
        var ii='c0'+thecid;
        newcommhtml += '<section class="c-content">';
        newcommhtml += '<a href="#" onclick="cButton(\''+ii+'\');" style="color:black;">x</a>';
        newcommhtml += '<p>'+nl2br(textval)+'</p> </section></div>';        
    });
})()
