我在html中动态添加一个按钮,如下所示:点击该按钮,我想调用一个Javascript函数:

var but = document.createElement("button");

but.value="delete row";

but.setAttribute("onclick","callJavascriptFunction()");
//this is not working

but.onclick="callJavascriptFunction()"
//this is also not working

document.getElementById("but").onclick="callJavascriptFunction()"
//this is also not working

but.id="but"+inc;

有没有办法解决这个问题？Plz帮助我.,提前谢谢
