I figured it at last! I needed to use ControlType->InputField

These are 2 simple examples of how to use InputField inside Manipulate.  I 
am not sure yet which is 'better', i.e. if I needed to use Intepretation to 
make sure the expression is not somehow gets evaluated, or may use use 
HoldForm on it, may be HoldForm is the safest way. I'll play more with it. 
But here is the basic idea:

example 1
-----------
process[eq_] := Text[eq]
Manipulate[process[name], {name, 3*x^2, ControlType -> InputField[]}]


or user Interpretation:
example 2
-----------

process[eq_] := Text[eq]
Manipulate[process[name], {name, Interpretation[3*x^2, 3*x^2],
   ControlType -> InputField[]}]

or use HoldForm:
example 3
------------
process[eq_] := Text[eq]
Manipulate[process[name], {name, HoldForm[3*x^2],
   ControlType -> InputField[]}]
