onclick on control with eval dosn't work

Hi,
I have an aspx control with works perfectly:
<asp:HyperLink ID="lnkSeekJob" runat="server" Text="Søgt job" NavigateUrl='<%# "SeekJob.aspx?id=" + Eval("companyPId")%>' Target="SeekJob" name="SeekJob" onClick="wopen('SeekJob.aspx?id=3', 'popup', 600, 480); return false;" />
The problem is that the id isn't always 3 - so I have to get the rows id - I try this with eval:
<asp:HyperLink ID="lnkSeekJob" runat="server" Text="Søgt job" NavigateUrl='<%# "SeekJob.aspx?id=" + Eval("companyPId")%>' Target="SeekJob" name="SeekJob" onClick='<%# "wopen('SeekJob.aspx?id=" + Eval("companyPId") + ", 'popup', 600, 480); return false;"%>' / ...
