.prob() does not change the checkbox status from inside each() loop : I'm working on a project where I want to check checkboxes based on matching a regEx Pattern. [MY_JSFIDDLE][1]

I come across a very strange behavior:

    function checkRegEx() {
    	$.each(myjson, function (i, v) {
    		var feedname = this.name;
        var regExPat1 = document.getElementById('regExField').value;
        var regExPat = new RegExp(regExPat1, 'gi');
        var matched_bool = regExPat.test(feedname);
        //console.log(matched_bool==true);
        if(matched_bool==true) {
        	$("#"+feedname).prop('checked',true);
          //$("#"+feedname).click(); // THIS WORKS STRANGELY
          console.log($("#"+feedname).prop('checked'));
        	//console.log("eval TRUE #" + feedname)
        } else {
        	$("#"+feedname).prop('checked', false);
        	//console.log("eval FALSEE #" + feedname)
        };
      });
      document.getElementById("regExField").focus();
    };

I can change and read out the status of the checkbox but it won't affect the GUI.
When I use `$("#"+feedname).click();` it works as I would expect. So I'm calling the ID right. I'm working on the latest Chrome. Strangely I found another [jsfiddle][2]. Here the `prop` method works for me. So it can't be a browser issue.

(im aware that jsfiddle uses jquery_edge, that is not the reason why it works there and not in mine- I tested different jquery versions in both jsfiddles)

Any advice. Can't see what I'm doing wrong here.
