MVC multiple forms on single view not working - asp.net-mvc

Question

I have 2 forms on a single razor view that open in seperate dialog boxes. The forms are submitted using jquery post..
First form works perfectly but the second form isnt recognised at all and when I try to serializr the data it returns an empty string.
Code below:
#using (Html.BeginForm("SaveElectricReading", "Store", FormMethod.Post, new { id = "frmSaveElectricReading" }))
{
<div id="electricDialog" style="display: none;" title="Electric Readings">
<p>
Please ensure the electric readings have been entered!
</p>
<table width="100%">
<tr>
<th>
Serial:
</th>
</tr>
<tr>
<td>
<input type="text" name="Serial" />
</td>
</tr>
<tr>
<th>
Reading:
</th>
</tr>
<tr>
<td>
<input type="text" name="Reading" />
</td>
</tr>
<tr>
<th>
Comment:
</th>
</tr>
<tr>
<td>
<div class="textwrapper">
<textarea rows="5" cols="10" name="Comment"></textarea>
</div>
</td>
</tr>
</table>
</div>
}
#using (Html.BeginForm("SaveWaterReading", "Store", FormMethod.Post, new { id = "myform" }))
{
<div id="waterDialog" style="display: none;" title="Water Readings">
<p>
Please ensure the water readings have been entered!
</p>
<table width="100%">
<tr>
<th>
Serial:
</th>
</tr>
<tr>
<td>
<input type="text" name="WaterSerial" />
</td>
</tr>
<tr>
<th>
Reading:
</th>
</tr>
<tr>
<td>
<input type="text" name="WaterReadingsdfsdf" />
</td>
</tr>
<tr>
<th>
Comment:
</th>
</tr>
<tr>
<td>
<div class="textwrapper">
<textarea rows="5" cols="10" name="WaterComment"></textarea>
</div>
</td>
</tr>
</table>
</div>
}
function showWaterDialog() {
var $dialog = $('#waterDialog').dialog({
autoOpen: false,
modal: true,
width: 400,
height: 400,
buttons: {
Submit: function () {
// $('#frmCreateStore').submit();
var data = $('#frmSaveWaterReading');
$.post("/Store/SaveWaterReading",
$("#frmSaveWaterReading").serialize(),
function () {
$("#waterDialog").dialog("close");
});
//$(this).dialog("close");
},
Cancel: function () {
$(this).dialog("close");
}
}
});
$dialog.dialog('open');
}

In the jquery function for showing the dialog with the form in it, I needed to add that dialog content to the second form on the page as follows:
$("#waterDialog").parent().appendTo($("form").eq(1)[0]);
