Execute Stored Procedure using Entity framework

I want to execute this Procedure using entity framework

/****** Object:  StoredProcedure [dbo].[ProjectTableRowCount]    Script Date: 12/27/2013 16:23:55 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROC [dbo].[ProjectTableRowCount]
( 
	@ProjectId int,
	@SearchKey varchar(50) ,
	@PageNo int , 									
	@PazeSize int 
)
AS
BEGIN

SELECT  AllTableInfo.Id , AllTableInfo.tableName ,AllTableInfo.[rowCount] ,  AllTableInfo.isActive    FROM
( SELECT [Table].Id, TABLE_INFO.*, [Table].isActive,  ROW_NUMBER() OVER(ORDER BY [Table].isActive) AS rownumber FROM [Table]  
INNER JOIN  
(
SELECT      A.Name 'tableName', SUM(B.rows) AS 'rowCount'
FROM        sys.objects A
INNER JOIN  sys.partitions B ON A.object_id = B.object_id
WHERE       A.type = 'U' 
GROUP BY    A.schema_id, A.Name
) AS TABLE_INFO

ON  [Table].tableName = TABLE_INFO.tableName ) AS AllTableInfo
INNER JOIN ProjectTable	ON
ProjectTable.tablesId = AllTableInfo.Id
WHERE ProjectTable.ProjectId = @ProjectId 
AND AllTableInfo.tableName LIKE '%'+@SearchKey +'%'           
AND rownumber > (( @PageNo -1) * @PazeSize )
                         AND rownumber <= ((@PageNo - 1)* @PazeSize)+ @PazeSize

END

my Entity code

public virtual ObjectResult<ProjectTableRowCount_Result> ProjectTableRowCount(Nullable<int> projectId, string searchKey, Nullable<int> pAGENO, Nullable<int> pazeSize)
        {
            var projectIdParameter = projectId.HasValue ?
                new ObjectParameter("projectId", projectId) :
                new ObjectParameter("projectId", typeof(int));
    
            var searchKeyParameter = searchKey != null ?
                new ObjectParameter("SearchKey", searchKey) :
                new ObjectParameter("SearchKey", typeof(string));
    
            var pAGENOParameter = pAGENO.HasValue ?
                new ObjectParameter("PAGENO", pAGENO) :
                new ObjectParameter("PAGENO", typeof(int));
    
            var pazeSizeParameter = pazeSize.HasValue ?
                new ObjectParameter("PazeSize", pazeSize) :
                new ObjectParameter("PazeSize", typeof(int));
    
            return ((IObjectContextAdapter)this).ObjectContext.ExecuteFunction<ProjectTableRowCount_Result>("ProjectTableRowCount", projectIdParameter, searchKeyParameter, pAGENOParameter, pazeSizeParameter);
        }

But the error is

"The function import could not be found in the container"


I add the function import by the information given on
http://msdn.microsoft.com/en-us/library/bb896231.aspx

Please help ...
