How to get value from input tag in python ? I've created input tag with id and name, but whatever i try to get it in python( tried self.tag_id or self.tag_name ) i get error that object like this does not exist.

Below code of my xml.

	<record model="ir.ui.view" id="training_test_form_view">
			<field name="name">Training Test Form View</field>
			<field name="model">training.test_online</field>
			 <field name="priority" eval="5"/> 
			<field name="arch" type="xml">
				<form string="Training Form" create="false"
					delete="false">
					<sheet>
						<field name="question" nolabel="1" readonly="1"/>
						 <group>	
						 	<input id="cliked_1" name="answer" type="radio"> <field name="answer1" nolabel="1" readonly="1"/></input> 
						 	<input id="cliked_2" name="answer" type="radio"> <field name="answer2" nolabel="1" readonly="1"/></input> 
						 	<input id="cliked_3" name="answer" type="radio"> <field name="answer3" nolabel="1" readonly="1"/></input> 
						 	<input id="cliked_4" name="answer" type="radio"> <field name="answer4" nolabel="1" readonly="1"/></input> 
						 </group>  
						 
						<button name="next" type="object" />				 
					</sheet>
				</form>
			</field>
		</record>
		

and exmaple code in python which is giving error

 @api.one  
 def next(self):
     print self.clicked1
    

Do i need to get it by self, context, js, or how ?
