Changing LABEL value by JQuery or Javascript does not work in ASP.NET

Navigation
3

I use this JS function in ASP.net: 

function habilitado(){
    var b = document.getElementById('<%= Label4.ClientID %>').value = "Habilitado";
}

I call it that in codebehind. The label value should be changed, but this does not happen. Can anyone help?

Note: I have already tried $(document).ready(function() at the beginning, and it still does not work. 

ClientScript.RegisterClientScriptBlock(this.GetType(), "teste", "<script language=\"javascript\">habilitado();</script>");
ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "teste", "<script type='text/javascript'>habilitado();</script>", true);

The value option is not applicable for labels. Try switching to innerHTML . So:

document.getElementById('<%= Label4.ClientID %>').innerHTML = "Habilitado";

With jQuery it can be done like this: 

$('#<%= Label4.ClientID %>').html("Conteúdo novo...");

The .value f% of javascript is only useful in elements <input /> and the .innerHTML should be used when you want to get / modify the internal content of some element, such as div's, label's and span's.
