PIC32MX795F512L External Interrupt-1 (INT-1) Problem??

[xpress_embedo]

Hello!!! i am trying to use the PIC32MX795F512L External Interrupt, i am using XC32 compiler and MPLAB X IDE.
As most of you are aware of legacy libraries coming with compiler, so i dont want to use the old ones, i want to use the new ones.
but my code is now working with the new one, and working with the old one, here is my code for both cases.

OLD ONE

//ISR
void __ISR(_EXTERNAL_1_VECTOR,IPL6SOFT) External_Interrupt_1(void)
{
    mINT1ClearIntFlag();
}
 
 
//Main
    mINT1SetIntPriority(6);
    mINT1SetEdgeMode(0);
    mINT1IntEnable(1);

When using the New Library, it is as follow:-
NEW ONE

//ISR Code
void __ISR(_EXTERNAL_1_VECTOR,IPL6SOFT) External_Interrupt_1(void)
{
  INTClearFlag(INT_SOURCE_EX_INT(INT_INT1));
}
 
//In main
/*
     * Enable External Interrupt-1
     */
    /*Interrupt on Falling Edge*/
   ConfigINT1(FALLING_EDGE_INT);
    //
    /*Enable External Interrupt-1 Priority to Level-6*/
    INTSetVectorPriority(INT_VECTOR_EX_INT(INT_INT1),INT_PRIORITY_LEVEL_6);
    /*Enable External Interrupt-1 Sub-Priority to Level-3*/
    INTSetVectorSubPriority(INT_VECTOR_EX_INT(INT_INT1),INT_SUB_PRIORITY_LEVEL_3);
    /*Clear External Interrupt-1 Interrupt Flag*/
    INTClearFlag(INT_SOURCE_EX_INT(INT_INT1));
    /*Enable the External Interrupt-1*/
   INTEnable(INT_SOURCE_EX_INT(INT_INT1),INT_ENABLED);

The New one is not working, means on pressing a button i am not going in interrupt.
While the old one works.
I had enabled the Multivectored and Global Interrupt in my code.

Please reply as soon as possible.

The code you gived is not useful to debug.
If you give the Function content,maybe have solution.

They are the functions provided by the Microchip XC32 and MPLABC32 compiler, i cant give you the source code of these functions.
