triggering an onchange event of a select box
<p>I have a select box, which i can populate using two methods.</p>

<p>First - Just by selecting any one of the option in the select box.</p>

<p>Second - I have a link just beside the select box.Clicking this link takes me to a page2, which has the same options but as links in page2.When i click one of them , it populates the select box.</p>

<p>Selecting the option directly from the "select" triggers an onchange event in it.
But when i click the link, select my required option from that page, it does not trigger the onchange event in the select box.
I am not sure where i am doing a mistake.</p>

<p>Thanks in advance.</p>
