How can We prevent the Submit button action in MVC3?

I have faced a problem with the submit button in mvc34 razor view.I have added a row dynamically in jQuery to webgrid which contains one submit button to insert the row data in db.I want to validate the textbox of the row if empty pop up a alert and stop the action. When I tried to write like this

$('#btnInsert').click(function()
{
          if ($('#tbStudentName').val() == '') {
            alert('Please enetre!');
             return false;
           }
});

This Event is not at all firing in jQuery.Can we call the dynamically created submit button client click event in jQuery like above? I have written like this

function InsertClick(button) {
        if ($('#tbStudentName').val() == '') {
          alert('Please enetre!');
            return false;
            } 
}

but still the Controller Side FormAction method is firing. Could any one tell me the solution to prevent the action in server side?
