You access it using Request.Form as you currently are, the issue might be the fact that you're giving the component a "name" in the element and then attaching a different "name" via attr. Try removing one of the name allocations

JavaScript

function CreateTextbox(){
var $ctrl = $('<input id="txtExtPersons1" name="txtExtPersons1" class="form-fieldContractEntry"').attr({ type: 'text' });
 $("#holder").append($ctrl);
}

Only controls that have the runat="server" are accessible on code behind and this cannot be created on client-side. However, there is a work around.
If you want to pass some value from a client-side script-created control to code behind on some button click, pass this value to an asp:HiddenField through a client-side script via onClientClick event first. The code behind will then be able to receive this value through the asp:HiddenField control.
