Had a look at your code.

Some observations

Action function seems to be accepting only one parameter

 

<apex:actionFunction name="hitMe" action="{!updatingFiledetails}">
    <apex:param name="one" value=""/>
</apex:actionFunction>

 But your code sends 3 params to the function

 

hitMe(value1,value2,value3)

 can you correct this one ?

  action functiom also accepting three parameters i just not worte in the code which i shown you but i have passed in my real code like

 

<apex:actionFunction name="hitMe" action="{!updatingFiledetails}">
    <apex:param name="one" value=""/>
    <apex:param name="two" value=""/>
    <apex:param name="three" value=""/>
</apex:actionFunction>

If you need any help on how actionfunctionworks or how to pass parameters have a look at this example

How about using assign to with apexActionFunction

 

<apex:actionFunction name="hitMe" action="{!updatingFiledetails}" rerender="x">
    <apex:param name="one" value="" assignTo="{!variable1}"/>
    <apex:param name="two" value="" assignTo="{!variable2}"/>
    <apex:param name="three" value="" assignTo="{!variable3}"/>
</apex:actionFunction>

replace the variable names with your variable name 

 

Make sure you add a rerender attribute to actionFunction that is really important to pass the params
