当用户单击按钮（而不是page_loadcomplete）时如何调用javascript方法？

Question

Tried Google but couldn't find my answer, So posting it here.

SS is attached in last. When the user clicks on download button, some actions performed on backend ie file transfer and when the process is completed, it changes the label text of "Total"

I want to change the label text of the div.

I have tried "RegisterStartupScript" also in place of "RegisterClientScriptBlock"

But didn't work

Tried by setting innerHtml from c# also didn't work

C#

protected void btnrepeat()
{
     //my code for load balancing
     Page.ClientScript.RegisterClientScriptBlock(GetType(), "myScript21211", "UpdateServerMax('" + server1max + "')", true);
     //LabelServer1Max.InnerHtml = server1max.ToString();
}

JavaScript

function UpdateServerMax(server1Max) {
     alert("njk");
     LabelServer1Max.innerHTML = server1Max;
}

HTML

<div class="col-md-2 col-sm-4 col-xs-6 tile_stats_count" style="margin-bottom: -1%">
<br />
<span class="count_top"><i class="fa fa-user"></i>Total </span>
<div class="count" id="LabelServer1Max" runat="server">
            4,567</div>
</div>

Also tried removing runat="server" from div.

Here is the SS what i want to change. https://ibb.co/kZ2Zvk

The 4th label says "Total".

You can update the value from C# after the Page_Load event.It can be somethig like this

protected void Page_Load(object sender, EventArgs e)
{
  LabelServer1Max.Text= server1Max;
}

or after the Page_LoadComplete Event

void  Page_LoadComplete(object sender, EventArgs e)
{
   LabelServer1Max.Text= server1Max;
}

Add it to your .cs file.
