Deleting the whole text only deletes the last character in the buffer

[Dina-Nashaat]

BUG:
If I select all text and then delete with a backspace, only the last character is deleted in the buffer, and the autocomplete still shows with the highlight.

SOLUTION:
Adding a trigger on keyup seems to solve the problem.

add this line in initTextarea (line 97)
elmInputBox.bind('keyup', onInputBoxKeyUp);
and add a new function (line 392)

        function onInputBoxKeyUp(e) {
            if (e.keyCode === KEY.BACKSPACE) {
                syntaxMessage = getInputBoxValue()
                if(!syntaxMessage){
                    resetBuffer();
                    hideAutoComplete();
                }
                return;
            }
        }
